Questions about our products?

HC103M2 is a capacitive humidity sensor with very short response time even at very low temperature. By this, the sensor is ideal for accurate measurement in the upper atmosphere with radiosondes and weather balloons.

The sensor is manufactured in state of the art thin film technology and is appropriate for SMD assembling. The design and the choice of materials leads to excellent linearity, high sensitivity and reproducible temperature dependence, which facilitate considerably the design in.

HC103M2 is supplied on tape and reel appropriate for standard SMD assembly machines.

  • What is the difference between a 2 wire and a 3 wire current output?

    Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
