Industrial Digital Temperature Controller Manufacturers

As a China-based Temperature controller manufacturer, Jiangsu Zhaolong Electrics Co., Ltd. designs and builds industrial digital temperature controllers for machinery, ovens, furnaces, incubators, chemical process lines and automatic temperature control systems. The electronic control range has been jointly developed with R&D institutions and academies in Shanghai, and is produced within the same production base as our temperature sensors and transmitters.

Jiangsu Zhaolong Electrics is a regional high-tech enterprise and a production base for temperature sensors and temperature control instruments. Our controller family covers compact 48×48 mm PID instruments, high-precision LCD intelligent PID controllers, and the widely installed XMT intelligent analogue thermostat series. Standard units accept K, E, J, Cu50 and PT100 inputs, use relay output for switching heating or cooling loads, and can be configured for OEM or special-specification projects.

What Our Temperature Controller Range Covers

We position the controller range as the electronic decision layer in a complete temperature loop. Each model is selected around the sensor input, scale range, output load and panel cutout required by the machine builder or plant engineer.

Application and Process Fit

Temperature control is a core requirement in manufacturing, food processing, laboratories, power generation, metallurgy, building materials and petrochemical plants. We specify controllers where a thermocouple or RTD reading must be converted into stable heating or cooling action: extruder barrel zones, drying ovens, incubators, environmental chambers, heat-treatment furnaces, autoclaves, packaging machinery and process skids.

For chemical, natural gas, petrochemical and daily chemical installations, the controller is often one part of a larger measuring loop. We regularly supply controllers together with our temperature sensor range and temperature transmitter range so the sensor, signal conversion and control are dimensioned together.

Control Approach and Configuration Options

Configuration starts with the process rather than the panel size. We need to know whether the output will drive a contactor, solid-state relay, solenoid valve or analogue converter, because that determines the output stage and the control method.

• Setpoint scale and resolution based on the working range required by your process.
• Input type matching thermocouple or RTD, including K, E, J, Cu50 and PT100.
• Control logic: simple on/off or PID; intelligent models provide PID, HART, 4–20 mA, 0–10 V and time-ratio options.
• Relay output up to 3 A for direct switching of small loads; larger loads are handled through a contactor or solid-state relay.
• Panel size and cutout, including 48 × 48 mm, 72 × 72 mm and XMT series formats.
• AC 220 V power supply and OEM requirements such as custom range, input type, output stage, colour and markings.

Accuracy, Testing and Quality

Our factory calibration and test laboratory provides a resolution up to 0.01 °C, a calibration range from -200 °C to +2000 °C, and reference-environment temperature control within ±0.1 °C. The standard PID families are graded with precision values of 1.5, while the XMT intelligent series is available with a precision value of 0.5 for more sensitive incubation and chamber control.

Each product undergoes comprehensive testing before leaving the factory. Jiangsu Zhaolong Electrics holds ISO9001 and CE certification and has obtained multiple invention and utility patents in temperature measurement and control technology; relevant controller models also carry RoHS, GB and CCC certification where applicable.

Installation, Maintenance and Project Support

Support extends beyond the controller itself. Our engineers design and install automatic temperature control boxes, temperature control rooms and remote monitoring temperature control systems for projects of different scale. For hazardous-area sensing, explosion-proof thermocouples and RTDs are separately certified; the controller is normally mounted in a safe-area panel or control cabinet.

For complete systems, our scope includes assembly, wiring and system verification before delivery. We coordinate the interface schedule with your process team so the controller matches the heater, cooler and sensor on site. Spare parts, calibration service and warranty support are handled directly by our service team, and replacement units can be kept available for production-critical equipment.

Information We Use to Configure Your Solution

To prepare an accurate configuration and quotation, our engineering team needs the working point of the process rather than only a part number. Please include the following project data with your enquiry.

• Machine, furnace, oven or chamber type and thermal load.
• Sensor input and measuring range: K, E, J, Cu50 or PT100.
• Setpoint range, required control accuracy and ambient conditions.
• Output requirement: relay up to 3 A, contactor or SSR drive, 4–20 mA, 0–10 V, HART or time ratio.
• Panel cutout size and available mounting depth.
• Power supply voltage and frequency.
• Display language, alarm and setpoint protection requirements.
• Quantity, OEM marking needs and target delivery location.

Send these details through our enquiry channel and we will respond within 12 hours with a model recommendation, configuration confirmation and commercial terms.

Frequently Asked Questions

Which temperature sensors work with your controllers?

Our controller range accepts K, E and J thermocouples and Cu50 or PT100 resistance sensors. The XMT intelligent series is configured with multi-input capability for flexibility across incubators, chambers and production equipment. If you already have a sensor installed, send us the type and measuring range so we can match the controller scale and input accordingly.

Can you customize a controller for OEM equipment?

Yes. Customized production is a core part of our business. We adjust the setpoint range, sensor input, output stage, panel size, colour and markings around the parent machine. Non-standard specifications can be developed from your drawings or samples, and for larger projects we also build complete temperature control boxes and control rooms.

Do your controllers provide analogue output or only relay output?

Intelligent models support PID control with relay contacts, 4–20 mA, 0–10 V, HART and time-ratio options. Compact models provide relay output up to 3 A, which suits direct switching of small heater or cooling circuits. Larger loads can be interfaced through a contactor or solid-state relay specified in your enquiry.

What documentation is supplied with the controller?

We provide the certificates applicable to the model, including ISO9001, CE, RoHS, GB and CCC where relevant. Calibration and test documentation is prepared during factory testing and covers the configured input range and output settings. Export packing and delivery terms are confirmed in the quotation.

Can you quote sensor, transmitter and controller as one package?

Yes. As a production base for temperature sensors and temperature control instruments, we can quote the complete loop: thermocouple or RTD, signal conversion if required, controller and the necessary accessories. This is a common approach for control cabinet builders and process equipment manufacturers, and our complete instrument line is available for review in the product category.
