PY861 Precision Pressure Sensors

PY861 pressure sensor has a microcontroller, 24-bit A/D converter, temperature sensor, etc., DC power supply, can be through RS232 and RS485 and computer communication. At the same time, it can also be used with our pressure calibrator for calibrating pressure transmitters and pressure gauges. Pressure measurement error is not affected by the ambient temperature and has nothing to do with the host computer, the product itself shows the real and reliable value.

Applications:

■ High-precision Pressure Controller Calibration Module
■ High-precision Leakage Measurement
