HD248 Temperature Transmitter – RTD & Thermocouple Input for Industrial Monitoring

The HD248 temperature transmitter adopts micro-machined silicon sensor technology and micro-power design. It offers internal span and zero adjustment buttons for on-site recalibration. The transmitter outputs temperature signal via RS485 MODBUS (or 4-20mA / HART) to control room, significantly reducing field installation wiring costs.
