The HART protocol superimposes audio digital signals on 4~20 mA analog signals. The digital signal amplitude is 0.5 mA and the data rate reaches 1200 b/s. 1200 Hz represents logic "1" and 2200 Hz represents logic "0". Enables two-way digital communication. HART communication has the characteristics of simultaneous point-to-point 4 ~ 20 mA analog and digital communication, multi-station communication methods, and multiple transmissions.The HT1200M is compatible with the SYM20C15 and HT20C15 and with ON OnSemi's A5191HRT and HT2015.

A temperature transmitter is an instrument that converts a temperature variable into a transmittable standardized output signal, and is mainly used for the measurement and control of industrial process temperature parameters. The current transmitter converts the AC current of the main circuit under test into a standard signal of constant current loop, and sends it to the receiving device continuously.

The temperature transmitter is mainly used for temperature measurement, and the following aspects should be paid attention to when selecting models.

NCS-IF105 converter Quadruple Channel Current 4-20mA to Fieldbus Converters As intelligent transition device, NCS-IF105 converter receives 0~20mA or 4~20mA analog signal (4 channels) and converts into fieldbus signal. NCS-FI105 converter uses digital communication technology, and makes the interface between field device and controller easier, and reduces the expense of installation and maintenance.

The installation environment of the integrated temperature transmitter must be within -20-+70°C. When the ambient temperature is too high, the signal converter and display module can be installed separately from the thermal resistance or thermocouple. To be equipped with a special explosion-proof box for separately mounting the transmitter.

Pressure transmitter is a device that converts pressure into pneumatic signal or electric signal for control and remote transmission.

Absolute pressure transmitter used for measurement of the liquid, steam, gas or atmospheric.
