Differential Pressure Sensor HPT-7

I. Description

The differential pressure transmitter adopts high-precision and high-sensitivity diffusion silicon differential pressure core body. Through the stable and

reliable amplifier circuit with strong anti-interference ability, the differential pressure signal of the measured medium is converted into standard analog

signal or digital signal. The exquisite packaging technology and perfect detection technology ensure the excellent performance of the product. It is

widely used in petroleum, chemical, metallurgy, environmental protection and measurement Automation control engineering and production process testing

and other industrial automation fields。

      III. Definition of wires

IV. Wire connection

1. 1. Screw out the screw and pull out the Reismman connector

2. 2. Pry out the junction box from the removal slot with a slotted screwdriver

3. 3. Insert the cable from the outlet and define the wiring according to

4. the terminal corresponding to the output signal

5. Assemble and restore the Reismman connector and tighten the wire cap

V. Notice

Ø Do not measure media that is not compatible with the transmitter material；

Ø Ensure that the power supply voltage meets the product requirements,

Ø and connect according to the instructions；

Ø The transmitter should be installed in a ventilated and dry place

Ø to avoid direct illumination and rain；

Ø Pay attention to use snakeskin pipe or iron pipe to protect the outgoing cable,

Ø or raise the cable rack；

Ø It is suggested that the product should be powered on for at least 10 minutes, and the product

Ø performance can reach the optimal level；

Ø When disassembling the transmitter, make sure that the pressure source is turned off to prevent the medium from ejecting；

This product is not explosion-proof. It will cause serious accident when used in explosion-proof area ；
