As a strong Shenzhen PCB cloning company, Dongdao Technology has been engaged in the fields of PCB reverse engineering, chip decryption, circuit board cloning, PCB cloning, and prototype debugging. It has successfully completed numerous projects in various fields, such as medical equipment, mechanical equipment, automation equipment, broadcasting and television equipment, communication equipment, instrumentation, environmental protection equipment, printing equipment, home appliances, and transportation equipment, earning consistent praise from customers. The cloning and development of multi-point thermometers is a typical successful case of Dongdao Technology's reverse research in Shenzhen PCB cloning. The following is an introduction to the multi-point thermometer:

Intelligent Multi-point Average Thermometer is suitable for scenarios where temperature gradients are not significant on the production site, and the average of multiple positions or multiple measurements at different positions needs to be taken. It automatically determines the liquid level and outputs the average temperature of the temperature probes inside the liquid.

The Intelligent Multi-point Thermometer is widely used in:

• Temperature measurement at different heights inside large oil tanks in oil fields and refineries, including various vertical tanks, horizontal tanks, storage tanks, and floating roof tanks.
• Temperature measurement at different liquid levels inside various storage tanks in chemical plants.
• Temperature measurement at different material levels in large grain silos.
• Prevention of spontaneous combustion and fire in large stacking/filling areas.
• Other applications where multiple temperatures need to be measured at different heights.

Its temperature measurement accurately reflects the average temperature inside the tank, better coordinating with the heating system operation and saving energy.

Performance Indicators:

• Operating Power Supply: DC 16~32V
• Temperature Measurement Range: -20℃ to 120℃, Measurement Accuracy: ±0.5℃
• Length of Measurement Probe: 1~30 meters, Maximum Number of Measurement Points: 120

Signal Output Interfaces:

• Two customizable 4-20mA current outputs: can be set to correspond to any measurement point.
• RS485/MODBUS communication: upload all temperature data.

Electrical Connection: M20 internal thread

Medium Temperature: -55℃ to 125℃, Medium Pressure < 4MPa

Explosion-proof Rating: ExdⅡBT4

Protection Level: Head IP65, Probe IP68

Installation: Flange installation or internal thread installation; customized installation methods are available for special occasions such as external floating roof tanks.

Technical Parameters:

• Number of Measurement Points: 1-16
• Single-point Temperature Measurement Accuracy: 0.5°C
• Single-point Temperature Measurement Resolution: 0.1°C
• Signal Output: 4-20mA, 485 Digital Signal.

The overall system consists of: temperature measurement cable + multi-point temperature acquisition + tank-side display + intelligent transmitter (outputs 4-20mA)

Introduction:

The thermometer adopts the method of bimetal thermometer, thermocouple, or thermistor integrated temperature transmitter, which not only meets the temperature measurement requirements on-site but also satisfies the long-distance transmission requirements. It can directly measure the temperature of liquid, vapor, and gas media as well as solid surfaces within the range of -80 to +500°C in various production processes.

Application: Used for measuring the temperature of various objects, with a wide measurement range, much larger than alcohol and mercury thermometers. It is suitable for high-temperature areas such as steelmaking furnaces and coking furnaces and can also measure low-temperature objects such as liquid hydrogen and liquid nitrogen.
