Specification

Outline Construction

(Unit: mm)

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.

Electric Connection

Cable Connection

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.
