Flameproof Temperature and Humidity Transmitter with Display – FTX-3000-TH

Flameproof Temperature and Humidity Transmitter with Display – FTX-3000-TH

Product Description :

FTX-3000-TH- Flameproof Temperature and Humidity Transmitter with Display.

Libratherm offers micro-controller-based Flameproof Temperature and Humidity Transmitter with Display field mount enclosure, for measuring and indicating Temperature and Relative Humidity in the field or in the process. The measured values are converted to the equivalent analog and digital values proportional to the Process Input for long-distance transmission and to interface to the PLC / HMI or DCS or any other field device.

Advantage of RS485 Interface:

Providing the feature of RS 485 digital serial interface is advantageous since the number of wires coming from the various sensors/transmitters can be avoided and instead, only two wires can be used to interface multiple such FTX-3000-TH on a serial port. Digital communication has the greatest advantage of exactly replicating the process value, that is what is measured at the plant and what is displayed in the control room always matches one to one as compared to transmitting the analog values. In today’s technology, most of the PLCs and DCS accept RS485 digital interface.

Key Features:

Microcontroller based design.
Accepts input from T + RH sensors.
Isolated single or dual 4-20mA output.
RS-485 MODBUS RTU serial interface.
Bright red / greenLED display.
IP 65 Flameproof Enclosure – suitable for Gas group I, IIA and IIB.
