Installation matters

1.4-20ma pressure transmitter ,Choose a place that is easy to operate and maintain for installation;

2.Install directly on the pipeline or equipment, and clamp it to the six sides of the transmitter with the wrench.

3.It should be installed as far as possible from the heat source;
4.It should be installed as far as possible from the vibration source;

Notes

1.Care should be taken when handling and installing the transmitter to avoid collision and affect the performance of the circuit.

2.If you encounter problems during the installation of 4-20ma pressure transmitter and use of the product, please contact our company. If there is any abnormality in the product, please do not open it for repair. Please contact the manufacturer in time.

3.The safety barrier shall obtain an explosion-proof certificate, and its installation shall be carried out in accordance with the requirements of its instructions.

4.The external thread of the transmitter must pay attention to the seal, otherwise the pressure will not be unstable.
5.There is an isolation diaphragm in the pressure inlet of the transmitter. Do not touch it with objects.
