Principles

Pressure transmitters are used to measure the pressure or level of gas, liquid or steam, and convert the measured signal into a 4-20mA standard current signal output through a digital amplifier.

There are many ways to debug pressure transmitters. In addition to local keypad debugging, HART handheld operator and HART transmitter debugging software can configure and set the parameters of the transmitter.

The self-diagnosis and remote diagnosis functions of pressure transmitters include sensor fault monitoring, internal inspection of various memories, watchdog monitoring, etc. Data will not be lost even in the event of a power outage. ‌ All these functions provide convenience for the daily maintenance of the transmitter, and also provide a basis for fault judgment and maintenance of the transmitter.

Explosion-proof protection grade: The transmitter is encapsulated in a sealed cast aluminum metal shell, suitable for various harsh environments and flammable and explosive environments, and the explosion-proof protection mark: Exd IIC T6; Exia IIC T6;
