One telemetry for various signals

Gone are the times in which a separate transmitter unit is needed for each sensor type. The Dx transmitter unit has universal signal conditioning that supports different types of sensors.

Temperature

Strain gauge

Voltage

Wide temperature range

Whether hot or cold: The Dx transmitter unit works reliably in a wide temperature range.
Standard from -40 °C to +85 °C and with the extended temperature range from -40 °C to +125 °C.
