Product Overview:
HPM289 High Temperature Protected Pressure Transmitter adopts high temperature resistance pressure sensor as signal measurement element, and is also processed through function compensation within wide temperature range . This product is processed through long-term and strict ageing testing and stability testing to achieve great stability and reliability. HPM289 is two-wire 4-20mADC signal output with digital screen display, which can be used in the occasion required measured pressure displayed on scene in hostile environment. It is widely used in machinery, metallurgy, petroleum, chemical and power industries to measure pressure.
Features:
·Imported high temperature resistant pressure sensing core
·With heat exchanger design, the maximum temperature for measuring medium is 150ºC
·Aluminium alloy shell , shell ingress protection IP65
·With polarity reversal protection , overcurrent and overvoltage protection, meet EMI protection requirements
·Screen display optionally
·Great anti-jamming , long- term stability
