Outline Construction


(Unit: mm)

 

12VDC Piezoresistive Pressure Transmitter 2

 

The differential pressure transmitter has two air intakes, one high-pressure air intake, marked "H" and a low-pressure air intake marked "L". During the installation process, air leakage is not allowed, and the presence of air leakage will reduce the accuracy of the measurement.

Use maintenance

 

USE

1. The differential pressure transmitter is small size and light weight, it can be installed directly on the measuring point when installation, pay attention to check the sealing of the pressure interface to prevent the measurement accuracy from being affected by air leakage.

2. The transmitter can enter the working state by connecting the wires as required. When measurement accuracy requirements are high, the meter should be powered on for half an hour before entering the working state.

Maintain

1. Normal use of the transmitter requires no maintenance

2. Transmitter calibration method: When the pressure is zero, first adjust the zero point, then make the pressure to the full range, verify the full scale, and repeat until the standard is reached.

3. The regular calibration of the instrument should be operated by professionals to avoid damage.

4. The instrument should be storage at 10-30℃ and the humidity at 30-80% with a clean environment when you not use it.
