PT 22 | Electronet

Product Description

PT-22 Pressure Transmitter is a reliable and cost-effective solution for accurate pressure measurement of clear liquids and gases in industrial applications. It uses a piezo-resistive sensor to deliver a stable 4–20 mA DC or 0–10 V DC output proportional to the applied pressure. The transmitter supports a wide measuring range from 0.1 bar to 1000 bar with an accuracy of ±0.25% of full scale. Designed for durability, all wetted parts are SS-316 and hermetically welded for long service life. With fast response time (<10 ms), span and zero adjustment, and IP-65 weatherproof enclosure, it ensures dependable operation. The direct line mounting design makes the PT-22 suitable for most general industrial pressure measurement requirements.
