  • Cold Junction of a Thermocouple: Why It Really Matters and How CJC Works

    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...

  • Understanding Stainless Steel Emissivity: Values, Key Factors, and Measurement Guide

    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...

Industry knowledge

As an Intelligent temperature transmitter manufacturer in the Temperature transmitter range, Jiangsu Zhaolong Electrics Co., Ltd. designs and builds integrated transmitters that convert thermocouple, RTD, resistance and voltage signals into standardized 4-20 mA, HART or Modbus outputs for DCS, PLC and remote monitoring systems.

We are a production factory in Jiangsu, China, not a trading office. The same plant that manufactures thermocouples, RTDs, and temperature controllers also produces the intelligent transmitter line, so sensor matching, calibration, and system engineering are coordinated from one source.

What Our Intelligent Temperature Transmitter Range Covers

The category is built around two product configurations. Both accept the signal types that dominate industrial temperature loops, and both are ordered with the sensor range and output protocol specified for your line.

  • Full isolation integrated temperature transmitter: Provides isolated signal conversion for process temperature loops where electrical noise, ground-loop interference or input/output isolation are a concern.
  • Integrated temperature transmitter: Combines the temperature sensing element and transmitter electronics in one assembly. This gives a direct measurement-and-transmission function, reducing wiring points and installation time.

Application Fit by Industry

Intelligent transmitters are used wherever a thermocouple or RTD signal must cross into a control system as a stable, standardized value. Our common installations include oil refineries, chemical plants, natural gas facilities and daily chemical production lines.

Industry Typical measuring points Transmitter value
Chemical industry Reactors, heat exchangers, storage tanks Stable signal conversion and isolation support process safety.
Natural gas Pipelines, compressor stations Digital communication reduces routine field checks.
Petroleum refining Distillation columns, furnaces, process vessels High-temperature stability supports energy-efficient control.
Daily chemical Detergent, soap, personal care lines Repeatable temperature measurement improves batch consistency.

Beyond these sectors, our transmitters are supplied to power generation, metallurgy, building materials and mechanical equipment builders, where the sensor loop is often paired with our own thermocouples and RTDs.

Critical Specifications and Configuration

  • Sensor inputs: thermocouple, RTD, resistance and voltage, depending on the selected model.
  • Output signals: 4-20 mA, HART or Modbus, configured to your DCS or PLC interface.
  • Accuracy: ±0.1°C to ±0.5°C depending on sensor type and measuring range.
  • Factory calibration range: -200°C to +2000°C with resolution up to 0.01°C.
  • Construction: industrial-grade housings resistant to dust, moisture, vibration and temperature extremes.
  • Configuration options: full-isolation transmitter module or integrated sensor-transmitter assembly.

Integration with Your Control System

Every transmitter is an input point on a control system. We configure the output level, range and protocol so the device appears as a calibrated point on your DCS or PLC rather than a generic instrument that needs re-engineering on site.

With HART or Modbus, operators can read the process variable and perform remote diagnostics. For larger projects, we design and install automatic temperature control boxes, temperature control rooms and remote monitoring temperature control systems using our own thermocouples, RTDs and transmitters.

Quality, Calibration and Acceptance

Zhaolong Electrics operates under ISO 9001:2015 / GB/T 19001-2016, CE and ISO 14001 certification. We also hold national explosion-proof production qualification certificates for explosion-proof thermocouple and RTD assemblies, which supports hazardous-area sensor loops.

  • Each transmitter is tested before leaving the factory, and calibration certificates accompany orders.
  • Laboratory equipment includes precious metal high-temperature detection furnace, low-temperature detection tank and oil tank detection furnace.
  • Calibration resolution reaches 0.01°C, with temperature difference control within ±0.1°C.
  • A 12-month warranty covers non-human damage, and spare parts supply is maintained for fast replacement.

Information We Use to Configure Your Solution

To prepare a configuration and quotation, we need the conditions at the working point, not just the transmitter model. Provide the following data and we will define the range, calibration and mechanical arrangement.

Project input Why it changes the configuration
Sensor type and element Selects input circuit, cold-junction setting and calibration curve.
Measuring range Defines transmitter range, scaling and achievable accuracy.
Process connection, insertion length and thermowell Determines mechanical configuration for the sensor assembly.
Output protocol 4-20 mA, HART or Modbus interface to your DCS or PLC.
Power supply and loop load Confirms output drive and isolation requirements.
Hazardous area, ambient temperature and enclosure rating Selects housing and explosion-protection approach.

If the order is a replacement, include the existing model number, terminal connection and control system type. We use that information to match the loop configuration exactly.

Customization and Project Support

Customized production is our core business. We manufacture standard and special-specification transmitters and sensor assemblies from drawings or samples, and we support OEM/ODM projects with our own R&D team.

  • Special thermocouple and RTD assemblies for molten metal, cement plants, power plants and salt furnaces.
  • Integrated measuring loops combining our temperature sensors and intelligent transmitters.
  • Automatic temperature control boxes, temperature control rooms and remote monitoring systems.
  • Export packaging by sea or air from our Jiangsu base.

Frequently Asked Questions

Can your intelligent transmitter work with our existing thermocouple or RTD?

Yes. We configure the input for the sensor type, measuring range and connection method. Send the sensor specification or current model and we will confirm compatibility before producing the transmitter.

What output protocols do you support?

Our intelligent transmitters can be supplied with 4-20 mA, HART or Modbus output depending on the model selected. We set the protocol and range to match your DCS or PLC input card.

Can you supply the transmitter and sensor as one integrated assembly?

Yes. The integrated temperature transmitter combines the sensing element and transmitter electronics in one structure. We size the probe, process connection and electrical output for your specific measuring point.

How do you verify accuracy before delivery?

Each unit is factory tested and calibrated. Our calibration equipment covers -200°C to +2000°C with resolution up to 0.01°C, and temperature difference control within ±0.1°C. Calibration documentation is supplied with the order.

What information do you need for a quotation?

We need sensor type, measuring range, process connection, insertion length, output protocol, power supply and the operating environment. For replacements, include the existing model number and control system interface.
