If you have ever compared two thermocouples on the same pipe and watched them disagree by a few degrees, the sensor tip probably was not the problem. More often, the answer sits at the other end of the loop, in the terminal block where the thermocouple wires meet the instrument. That connection point is the cold junct...

If you have ever aimed an infrared thermometer at a stainless steel surface and received an unexpectedly low reading, emissivity is almost certainly the reason. Stainless steel is one of the most common materials in industrial plants, yet its emissivity ranges widely depending on how the surface is finished, how hot i...

Jiangsu Zhaolong Electrics Co., Ltd. is a Bimetallic pointer thermometer manufacturer with a production base in Jiangsu, China, and more than twenty years of experience in temperature instrumentation. We build this product line for plants that need local, mechanical temperature indication without external power, signal wiring or complex electronics. The range supports chemical processing, natural gas, petroleum and petrochemical, and daily chemical applications, and it is supplied worldwide through OEM projects and distributor partnerships.
Mechanical temperature indication where operators work
A bimetallic pointer thermometer uses a coiled bimetallic strip to rotate a pointer over a dial as temperature changes. The mechanism is self-contained, so the display remains readable during power loss and does not need a transmitter loop. That makes it a practical choice for local indication on pipelines, storage tanks, reaction vessels, compressor stations and similar points where the operator needs an immediate answer.
- Chemical processing - reaction vessels, storage tanks and pipelines where clear readouts and corrosion resistance are essential.
- Natural gas - transport lines, compressors and storage systems where electrical supply is not always available or desirable.
- Petroleum and petrochemical - refinery and processing plant temperatures under high loads, pressure swings and wide process variation.
- Daily chemical production - mixing, heating and storage of consumer chemicals where repeatability and easy reading matter.
Product range and configuration approach
Within this category we treat each thermometer as a configuration task. The usual starting data are measuring range, dial size, stem length, process connection and mounting direction. Axial, radial and adjustable-angle formats can be matched to the operator reading position, and special scales, stem lengths, threads and materials can be produced.
| Application | Typical installation points | Configuration priorities |
|---|---|---|
| Chemical processing | Reaction vessels, storage tanks, pipelines | Corrosion-resistant stem material, process connection match, thermowell compatibility |
| Natural gas | Transport lines, compressor stations, storage systems | Robust mounting, clear outdoor readability, secure connection |
| Petroleum and petrochemical | Refinery lines, processing vessels, heat exchangers | Wide temperature span, material compatibility, stable pointer movement |
| Daily chemical production | Mixers, heating jackets, storage tanks | Readability, cleanability, stable calibration over repeated cycles |
If the final installation needs an electronic display rather than a mechanical pointer, we also supply the Bimetallic digital thermometer variant within the same family. The parent Bimetallic thermometer range covers both mechanical and digital requirements.
Materials, mounting and environment
Material selection is driven by the process medium and the surrounding atmosphere. Stainless steel stems and connections handle the great majority of chemical, gas and petrochemical duties, while case construction should be matched to outdoor humidity, washdown and corrosive air. If the instrument is installed in a thermowell, we need the existing bore size and thread form so the stem fits correctly and can be removed without draining the process.
- Immersion depth - the sensitive element must be long enough to reach representative process temperature.
- Mounting orientation - axial, radial or adjustable display should place the dial where the operator actually stands.
- Vibration - compressor and line vibration should be discussed at inquiry so movement and case support can be selected accordingly.
- Range selection - the normal working point should sit near the middle of the scale, not at the upper stop.
Quality, calibration and long-term service
Jiangsu Zhaolong Electrics applies quality supervision across the production process and treats final testing as part of delivery. The company holds GB/T 19001-2016/ISO9001:2015 and CE certification, and our factory is equipped with testing and calibration facilities. Each product is inspected before leaving the factory.
- Factory testing before shipment.
- Calibration service and verification data based on your specified range.
- Spare parts supply for quick replacement and minimal downtime.
- 12-month warranty covering non-human damage.
Control integration and project support
Many projects use a mechanical pointer thermometer for local indication and a separate sensor or transmitter for the control room. We are a temperature sensor and control instrument manufacturer, so we can supply the complete loop: a bimetallic pointer thermometer for the operator, a temperature sensor for measurement, a transmitter for signal conversion, and a controller for automated action. We also design and install automatic temperature control boxes, control rooms and remote monitoring systems for small and large scale projects.
Information we use to configure your solution
Send these details with your inquiry so our engineers can prepare a complete configuration, drawing confirmation, calibration plan and quotation without unnecessary revisions:
- Normal operating temperature, expected maximum and the required scale range
- Process medium, working pressure and flow or agitation conditions
- Process connection size, thread standard or existing thermowell dimensions
- Required stem length, dial diameter and mounting orientation
- Material requirement for the stem, connection and case
- Environment: outdoor exposure, humidity, corrosive atmosphere or washdown
- Accuracy expectation and whether a calibration certificate is required
- Quantity, packaging, export delivery point and documentation language
- If part of a larger scope: signal output, alarms, control panel or remote monitoring needs
Frequently asked questions
What is a bimetallic pointer thermometer used for?
It is used for local temperature indication on pipes, tanks and vessels. The mechanical display requires no electrical power and remains readable during control system outages, which is why engineers keep this product on process equipment across chemical, natural gas, petroleum and daily chemical plants.
Can you customize the range, connection and stem length?
Yes. Customized production is a core part of our work. We manufacture instruments from drawings or samples, including special measuring ranges, process connections, stem lengths, dial artwork and protective features. The inquiry data in the section above lets us confirm the physical and thermal design before production.
Do bimetallic pointer thermometers need calibration?
Like all mechanical instruments, they can drift after long thermal cycling or heavy vibration. We offer factory calibration and can verify each unit against your specified operating points before delivery. For installed instruments, we provide calibration guidance and can supply replacement spare parts quickly.
Can you integrate this thermometer into a larger control project?
Yes. Alongside the bimetallic pointer thermometer, we manufacture thermocouples, RTDs, temperature transmitters, controllers and instrument accessories. We also design and install temperature control boxes, control rooms and remote monitoring systems, so the local dial and the electronic control loop can be supplied as one package.
What after-sales support is provided?
All products carry a 12-month warranty covering non-human damage. We provide calibration service, spare parts supply and responsive technical support. We reply to inquiries within 12 hours and can coordinate sea freight, air freight and export documentation from our Jiangsu facility.
