Features:


1. The digital pressure transmitters adopts imported diffused silicon pressure sensitive components and advanced diaphragm isolation technology to diffuse a Wheatstone bridge on the monocrystalline silicon wafer, and the measured medium (gas or liquid) is pressed to make the bridge wall A change in the resistance value (piezoresistive effect) produces a differential voltage signal.

 

2. The amplifier circuit adopts imported American BB integrated chip and is supplied with wide voltage;

 

3. Optional output signal: 4~20mA/ 0~5VDC/0~10VDC/1-5VDC/RS485;

 

4. Compact structure, convenient installation, strong anti-interference ability, lightning protection, reverse wiring and over-voltage protection, current limiting protection; fast response (2ms) and exquisite craftsmanship.

Installation Precautions:

 

1.     Less than 0.03MPa should be installed vertically to avoid affecting measurement accuracy;

 

2.     The wrench should be tightened from the hexagonal nut at the bottom of the transmitter during installation to avoid direct disconnection of the upper part of the transmitter.

 

3.     It is forbidden to measure media that is not compatible with stainless steel;

 

4.     Ensure that the power supply voltage meets the power supply requirements of the probe. The positive and negative voltages of the power supply correspond to the positive and negative wiring of the product, ensuring that the highest pressure of the pressure source is within the range of the product;

 

5.     During the pressure measurement process, the pressure should be slowly pressurized and relieved to avoid instantaneous addition to high pressure or to low pressure;
