Product overview

WPM-63 Differential Pressure Transmitter is based on 2 absolute pressure sensors, which can be used where differential pressure is more than 10% of the maximum pressure range. Because of the use of unconventional method of measuring differential pressure with 2 absolute pressure sensors, WPM-63 has completely different advantages from traditional differential pressure measuring elements. WPM-63 Differential Pressure Transmitter does not measure differential pressure directly but use 2 absolute pressure sensors to make indirect measurements. While reducing costs, this pressure transmitter also performs well under the circumstance of overpressure on one side. The differential pressure range should not be less than 10% of the maximum pressure range. There are 2 pressure ports on each side, so the product can be easily installed on pressure pipelines. Therefore, the differential pressure value can be accurately measured even in the case of a high ratio of pressure range divided by differential pressure. WPM-63 also adopts the microprocessor-based MSP430X, which enables digital error compensation to eliminate all repeatability errors (such as linearity and resistance dependence), and the sensor signal is measured by a 16-bit AID converter, so in the whole pressure range, each standard pressure range can gain 0.1% measurement accuracy.
