P-HC Pressure head measuring instrument
 
The digital intelligent pressure head measuring instrument is mainly developed for the testing needs of the water pump industry. It can be used in conjunction with a pressure sensor as a secondary instrument for testing pressure head. The pressure head measuring instrument has the advantages of high detection accuracy, fast real-time response and simple operation interface. This instrument adopts **-bit∑-△AD converter and high stability reference voltage, and is equipped with CPU and optodecouple isolation with strong anti-interference ability, and adopts various technologies such as software and hardware zeroing, which has the advantages of high precision, fast real-time response speed and easy operation.
This instrument is equipped with two input channels, matched with 4~*0mA pressure sensor, which measures two pressures at the same time. The pressure display units can be converted by the keypad to display megapascals and meters respectively.
The meter has an RS**2 serial standard interface, which can communicate with a computer.
â—† Input signal: two DC 4~*0mA;
â—† Measurement scale: *0.****9.9Mpa;
◆ Measurement accuracy:±0.2%;
â—† Manifestation mode: five positions of each of the two pressures;
â—† Output interface: RS**2 communication interface, baud rate ***0, can communicate with the computer online;
â—† The appearance is equipped with a two-wire pressure transmitter, and can also be used as a display terminal of the pressure transmitter;
â—† The surface supplies the sensor DC*4V power supply, and the two-wire wiring method.
