Digital pressure sensor with 3 separate channels for measuring P1, P2 and DP readings plus 2 temperature channels measured on the sensing diaphragm which is in close contact with the media. Base pressure ranges from 3 bar up to 300 bar with high accuracy.
Two absolute pressure sensors are digitally characterised and the readings subtracted within the sensors software to produce a high accuracy differential pressure reading. Since the sensor is digitally characterised over temperature as well as pressure the temperature reading for each absolute sensor can also be measured via the RS485 digital interface.
If supplied with the RS232 or USB converter box the PD39X twin absolute digital dp sensor can be used with PC software that has been custom designed for easy installation and operation with the sensor so that the user can be up and running on a computer within a few minutes. The PC software enables live readings to be displayed in real time for any of the measurement channels. The display window can also be configured to dispaly graph plots as the data is collected.
