Medium Wave Quartz Transmitter

Using a medium wave quartz transmitter, a heating coil heats the quartz glass tube, thereby activating the product. Depending on the temperature, you can see a deep red to bright orange glow.

In the mid- and long-wave infrared range, quartz infrared emitters have an emission range comparable to ceramic emitters. Only the short-wave radiation ratio below 3 µm of quartz infrared emitters has an effect. Therefore, despite the many overlaps, the range of applications for the two transmitter types is different. Due to their lower mass and their shorter reaction times, they are also recommended for cyclic or frequently interrupted processes. However, quartz transmitters are mechanically more susceptible and are not suitable for dusty or chemically aggressive environments. We distinguish between cassettes and individual test tubes.

Quartz Box

The quartz cell produces usable wavelengths between 1.5 and 8 µm and therefore emits light during operation. The cabinet is made of aluminized steel with excellent reflective properties.

Installation is usually done with M5 bolts. For compatibility with ceramic transmitters, quartz transmitters can be manufactured with junction boxes.

The box usually includes seven tubes. A thermocouple can be installed in the intermediate tube upon request.

Quartz glass tube

Our MWIR quartz glass tubes are custom made. They are used, for example, for radiant platens in toasters or drying systems. There are different connection options. Quartz glass tubes are available as light or dark emitters and are only suitable for horizontal operation.

Thermocouple

We can also install thermocouples in quartz boxes. It will be installed in the middle of seven quartz tubes. Usually it is a K-type thermocouple, but a J-type can also be used. Thermocouples cannot be installed in quartz glass tubes and STQH transmitters.
