This transmitter supports RTD and thermocouple inputs, linearizes the input signals and outputs 4mA to 20mA with accuracy ±0.1%FS of selected range. The DIP switch design makes configuration easily done on site as well as range and error programmable by computer software.
The surge and full pulse protection, input and output electrical makes the transmitter work stable and avoid the damage from the thunder or power supply voltage fluctuations from the high-power consumption equipment startups and stops. The low power consumption design decreases the drift from the temperature by the heat dissipation and improves its long-term stability.
The option of probe selections provides the convenience to the user for the whole measurement system. The calibration of transmitter and probe as a system provides the unbroken traceability chain to the data with uncertainty. The annual calibration service can guarantee the long-time use with reliable data.
