Instrument Overview
As an Explosion-proof differential pressure transmitter, it adopts an explosion-proof shell design and passes strict explosion-proof certification. This Explosion-proof differential pressure transmitter, equipped with a robust Differential pressure sensor, effectively prevents internal electric sparks or high temperatures from igniting external flammable media, making it ideal for hazardous areas like petroleum and petrochemical industries. In crude oil pipeline monitoring at refineries, the Explosion-proof differential pressure transmitter ensures safe, stable data collection, with its Differential pressure sensor guaranteeing accuracy for pipeline pressure balance control, thus avoiding pressure-related accidents.
The Differential pressure sensor, using an imported single-crystal silicon chip, delivers excellent linearity and long-term stability. Paired with intelligent temperature compensation, it operates stably in -40~85℃ environments, offsetting temperature impacts—vital for power industry boiler flue negative pressure measurement. This Differential pressure sensor, integral to the Explosion-proof differential pressure transmitter, High-pressure differential pressure transmitter, and Pipeline pressure transmitter, ensures accurate signal output even amid severe temperature fluctuations. The backlit LCD, compatible with multiple units, complements the Differential pressure sensor’s precision, allowing clear on-site data reading in dim conditions.
