Small high-temperature pressure transmitter selects high-precision, high-stability pressure sensor components, after highly reliable amplification circuit and precision temperature compensation, the measured medium's adiabatic or gauge pressure is converted into 4-20mA, 0-5VDC, 0-10VDC and 1-5VDC and other standard electrical signals.
Small high-temperature pressure transmitter compact size, all stainless steel shell, easy to install in complex places, process interface can be customized according to user requirements. It adopts universal DC24v power supply and outputs 2-wire 4~20mA signal with stable and reliable performance. Can be applied to the furnace, flue positive and negative pressure measurement. Small high-temperature pressure transmitter measuring pressure shall not be higher than 150% of the rated pressure, static pressure shall not be higher than 20KPa, differential pressure type high pressure end marked H, low pressure end marked L. ZR804H small high-temperature pressure transmitter only pressure type can be selected from the range from 0-200Pa ~ 60MPa, stainless steel shell isolation anticorrosive, compact design, installation is very simple.
Small high-temperature pressure transmitter is the use of foreign isolated sensor chip, developed by our factory a new type of pressure transmitter, using diffusion silicon or ceramic pressure sensor core, temperature compensation, digital signal processing and other advanced technologies and processes.
