Relative humidity sensors from Sensirion have become the market standard, since they were launched in 2002. Nowadays the company yearly sells millions of humidity sensors all around the world. The sensor solutions are designed for diverse applications such as data logging, climate control, and antifogging. They hence measure relative humidity and temperature in different kind of products. The digital humidity sensors work with a capacitive measuring principle. Thanks to its unique CMOSens technology, the humidity sensors allow precise humidity and temperature measurement at low cost.

HITY 2000 is based on impedance measurement rather than the capacitive method used by other systems. This technology offers an extremely high degree of resistance against aggressive chemical gases and provides stability for as long as 5 years, depending on the medium. The sensor reacts to humidity changes much faster than average.

PTC units for DIN bar application.
EH/FH heaters, installed separately from cooling unit, must be connected to TMC thermostat. When used to prevent cabinet condensate they should be eletrically connected also when cabinet is off.In this cabinet its better to install more heating elements with small heating power.In this way there is an optimal air temperature distribution.

HIGH TEMPERATURE SENSORS
Significant scientific and engineering enhancements in advanced materials, Pre-Process and In-Process production methods and in-site testing methods are driving the demand for displacement sensors that can handle extremely high temperatures up to 1832F (1000C). Contemporary producers of aircraft engine rotational alignment, plate glass, materials testing extensometry, continuous flow steel, now use standardized high temperature Capacitec sensor solutions for in-process applications to control the quality of their production on a real time basis. Qualification testing of disc brakes, jet engine dynamics and high speed shaft rotations also rely on Capacitec sensors. Advanced materials for automobiles, structural components, and aircraft are also tested for strength and durability with the use of Capacitec's line of extensometers and clip gauges.
High Temperature Major Applications:
- Disc brake testing
- Silicon Wafer processing
- Metal and Glass forming
- Jet engine thermal expansion
- Material strength testing
- Mold separation
- Turbine testing
- Strain Extensometry

Capacitive sensors (KAS) react to metals and non-metals that exceed a specific capacitance on approaching the active surface. The sensing distance with respect to a specific material is greater the higher the dielectric constant. The sensors are used to detect objects, for counting functions and for all types of level monitoring applications in liquid materials (i.e. water, oil, acids, glue) and bulk materials (i.e. pouder, granulate, pellets).

For demanding applications in high-temperature areas, inductive proximity switches with good long-term reliability have become increasingly popular. Contrinex offers a series of embeddable and non-embeddable HT switches in sizes M8 to M50. The devices have operating distances from 2 to 25 mm, and are respectively suitable for applications up to 140C, 150C, 180C and 230C.
The executions for 140C, 150C and 180C feature built-in amplifiers. Connections by means of a 2 m silicone or Teflon cable is standard. Other cable lengths and types are available on request.
For 230C types, the amplifiers are built into an M12 stainless-steel housing, which is connected by means of a standard 2 m Teflon cable, and thus removed from the hot area. This cable carries a pure DC, rather than a high-frequency signal, and its length can thus be chosen freely, without having a negative influence on the switching behavior of the device, and without the need for adjustment. Connection of the amplifier is by means of a 2 m PUR cable.
All the usual protection functions, such as short-circuit, overload and voltage-reversal protection are built in. Furthermore, the devices feature good protection against environmental influences (IP 67).

The capacitive high temperature sensors are especially suitable for applications where the sensor head is exposed to a high ambient temperature, or comes directly into contact with hot materials.
