COSMOWAVE TECHNOLOGY CO., LTD.

PT-105A-A / PT-103B-A Pressure Transducers with Built-in DC Output

These transducers are suitable for measuring the pressure of air or non-corrosive gases, offering a robust overpressure tolerance of up to 10 times the full scale (F.S.), ensuring safe operation. The measurement ranges include 0–200 Pa for the PT-105A-A and 0–500 Pa to 0–100 kPa for the PT-103B-A, accommodating a variety of applications. The built-in amplifier minimizes noise interference and ensures stable output.
■ Features
High Accuracy Measurement: Achieves ±0.15% F.S. accuracy, including linearity, repeatability, and hysteresis.
Excellent Temperature Characteristics: Temperature effects on zero point are ±0.03%/°C of F.S., and ±0.02%/°C on span.
High Overpressure Tolerance: Capable of withstanding up to 10 times the F.S. or up to 500 kPa, ensuring reliability under harsh conditions.
Fast Response Speed: 99% step response times are 300 ms or less for the PT-105A-A and 220 ms or less for the PT-103B-A, enabling quick measurements.
Robust Design: Features Rc 1/8 pressure port connections, facilitating easy integration into a wide range of systems.
