Vario and altimeter sensor (TEK)

Precision variometer, with altitude and variometer monitoring using two separate pressure sensors.
With its small size and weight of just 6.5 g the robbe TEK precision vario and altimeter sensor is presumably the world’s smallest, lightest and most accurate sensor (with dual TEK sensor *).

Features of the vario / altimeter unit:
- High sensitivity of 2 cm/s enables the device to exploit ultra-weak thermal lift, as it detects even the slightest hint of climb.
- As you would expect, this variometer is altitude-compensated (a change of pressure of 1mBar at sea level naturally indicates a different rate of climb at an altitude of 3000 m).
- Conversion of pressure into height according to Standard ICAO atmosphere, with an accuracy of 1 m.
- The TEK vario / altimeter sensor is particularly good at rejecting interference from 2.4 GHz telemetry transmitters.
- An uncompensated variometer simply shows the aircraft’s vertical speed, i.e. the pilot is alerted to climb or sink caused by control commands (known as “stick-induced lift”). The only factor which interests the glider pilot is the aircraft’s total energy: he wants to know whether the model is flying in lift or sink. This is accomplished by the use of an optional “Total Energy Compensation nozzle” which can be connected to the sensor.
- Can be updated via USB, i.e. software updates can be loaded by the user himself.
- The pressure element is mounted on a ceramic substrate, ensuring extremely low temperature drift and long-term drift of the pressure sensor.
