Product overview
The explosion-proof digital display AI-TD pressure transmitter uses a silicon pressure sensor with a stainless steel diaphragm as the signal measurement element and employs a dedicated IC circuit for zero-point and temperature performance compensation over a wide temperature range. This pressure transmitter features an LCD digital display and is explosion-proof certified.
This product is used for pressure measurement in industrial processes such as petroleum, chemical, metallurgy, power, and hydrology.
