DR3417 High Temperature Pressure Transmitter
DR3417 High Temperature Pressure Transmitter
The DR3417 high temperature pressure transmitter is designed for high and low temperature medium in the range of -40~150℃. In particular, the sensor consists of two diaphragms: a titanium alloy pressure sensing diaphragm and a titanium alloy measuring diaphragm. The pressure of measured medium is transmitted to the measuring diaphragm through the pressure sensing diaphragm, resulting in precise measurement results. The pressure transmitter provides a high precision signal processing circuit for converting the output signal of the sensor to a 4-20mA output. With the heat dissipation structure at the bottom of the transmitter, the sensor can obtain stable measurement results even at up to 150°C. it is the whole welding structure with the pressure accuracy of ≤0.5%FS and the temp. error ≤±0.025%FS/℃, the robust performance enables working in the hostile environment.

FAQ
Which applications is for temperature and pressure transmitters?
Generally, It is for steam and fluids pressure measurement such as applications in boiler, hot spring and hot thermal liquids and gases in chemical plants.
Does temperature affect pressure transmitter?
Both ambient and media temperature variation can affect a pressure transmitters’ performance potentially causing premature component failure or unstable readings.
What is a media temperature??
The media temperature specification refers to the minimum and maximum temperature that the transducers process connection and diaphragm can tolerate. Media is the liquid or gas being measured by the transducer.
