COSMOWAVE TECHNOLOGY CO., LTD.

PT-141C / PT-142B-A Gas/Liquid Compatible Gauge Pressure Transducer

The transducer employs an SUS630 stainless steel diaphragm with excellent corrosion resistance and durability in its pressure sensing element. The measurement range covers full scale from 50 kPa to 20 MPa in gauge pressure, making it suitable for a wide range of applications. It features high accuracy and excellent temperature characteristics, and a built-in amplifier minimizes the effects of noise.
■ Features
High-Precision Measurement: PT-142B-A achieves an accuracy of ±0.15% of full scale, and PT-141C achieves ±0.25%.
Excellent Temperature Characteristics: The temperature effect on the zero point is ±0.03%/℃ per full scale, and on the span is ±0.02%/℃.
High Pressure Resistance: It supports an allowable overpressure of 2 times the rated pressure for ranges of 5 MPa or less, and 1.5 times for other ranges.
Fast Response Speed: The 99% step response speed is 30 ms or less, enabling rapid measurement.
Robust Design: Utilizes an SUS630 stainless steel diaphragm with excellent corrosion resistance and durability, achieving a long service life.
