High Temperature Pressure Transducer Hessman Temperature
Transmitter Air Temperature Sensor
Description High Temperature Pressure Transducer Hessman
Temperature Transmitter Air Temperature Sensor
The temperature transmitter incorporates thermocouples and thermal
resistances as temperature measuring elements. The output signal
from these elements is transmitted to the transmitter module, where
it undergoes voltage stabilization filtering, operational
amplification, nonlinear correction, V/I conversion, constant
current generation, and reverse protection circuitry. These signal
processing steps result in the conversion of the temperature signal
into a 4-20mA current signal or a 0-5V/0-10V voltage signal, which
exhibits a linear relationship with the temperature. Additionally,
the transmitter is equipped with RS485 digital signal output
capability, enabling communication and data transmission in a
digital format.

Main features High Temperature Pressure Transducer Hessman
Temperature Transmitter Air Temperature Sensor
● It adopts silicone rubber or epoxy resin sealing structure, so it
is shock-resistant, moisture-resistant and suitable for
installation and use in harsh field environments.
● It can be installed in the junction box of thermocouple and
thermal resistance on site, and output signal of 4-20mA and 0-10mA
directly. This not only saves the cost of expensive compensation
wires, but also improves the anti-interference ability during
long-distance signal transmission;
● Thermocouple transmitter has the function of automatic
compensation of cold junction temperature;
● High precision, low power consumption, wide operating temperature
range, stable and reliable operation;
● Wide range of application, it can not only form an integrated
on-site installation structure with thermocouple and thermal
resistance, but also can be installed in testing equipment and
instrument panel as a functional module;
● The intelligent temperature transmitter can communicate with the
host computer through the HART modem or with the handheld and PC to
carry out remote information management, configuration, variable
monitoring, calibration and maintenance functions for the model,
graduation number and range of the transmitter;
● The intelligent temperature transmitter can adjust the display
direction of the transmitter according to the actual needs of the
user, and display the medium temperature measured by the
transmitter, the change of the sensor value, the output current and
the percentage;
