Resistance thermometers

Resistance thermometers are equipped with platinum thin-film measuring resistors according to DIN EN 60 751 as measuring element, which are embedded in stems made of sheathed, mineral insulated cable. The temperature-dependent change of resistance of the platinum is used as measuring effect and can be metrologically processed in the form of a relatively linear resistance signal. Depending on the construction type and the used measuring element, temperatures of -200 up to +800 °C (-328 to +1472 °F) can be measured with resistance thermometers. 

With resistance thermometers, the highest accuracies in the entire temperature measuring technology can be achieved. The accuracy classes AA, A and B according to DIN EN 60 751 are available for you as standard. 

We manufacture various resistance thermometers for all applications: resistance thermometers with connection head, sheathed resistance thermometers, compact resistance thermometers for the engineering industry, versions for air and surface temperature measurement and others.

Thermocouples

Thermocouples contain metallic wires made of different alloys according to DIN EN 60 584, which are welded to one another. Those wires are either embedded in stems made of sheathed, mineral insulated cable or electrically insulated by ceramic components. The thermoelectric effect, which results from the different material combinations, can be metrologically processed in the form of a temperature-dependent voltage. Depending on the construction type and the used material combination, temperatures of -200 up to +1600 °C (-328 up to 2912 °F) can be measured with thermocouples. 

Thermocouples are very robust, resistant to mechanical stress and can be manufactured in very small dimensions. Our thermocouples are supplied with accuracy class 1 according to DIN EN 60 584 as standard. 

We manufacture various thermocouples for all applications: straight thermocouples, sheathed thermocouples, multipoint thermocouples, versions for surface temperature measurement and others.

Explosion-protected resistance thermometers and thermocouples

Our explosion-protected temperature sensors are used for measurement, control and limit value monitoring of process temperatures and, depending on the model, are intended for the application in potentially explosive areas of zone 0 or 1 and 20 or 21.
The temperature sensors can be executed as ignition protection type “intrinsic safety” (i), “flameproof enclosure” (d) or “protection by enclosure” (t). A combination of the ignition protection types “intrinsic safety” with “flameproof enclosure” or “intrinsic safety” with “protection by enclosure” is possible as well. Optionally, the Ex d and the Ex t sensors can be equipped with an integrated process display. With the models TPtPAXd and TTePAXd, now a temperature-indicating 4-20 mA transmitter in a field housing with flameproof enclosure is available for our customers, which also features the ignition protection type “intrinsic safety”.

Digital thermometers

Local, battery-operated digital indicator in bayonet ring case

Local Indicator with Long Life Battery

The electronic thermometers of our new product line LILLY can be manufactured with the same construction types as bimetal or gas-actuated thermometers. Additionally, very short installation lengths and increased accuracies (0.3 % ±1 dgt ±sensor tolerance) are available. LILLY thermometers can be manufactured with a rigid stem (bottom stem position or back stem position), as turnable and adjustable version, and as remote reading thermometer with cable sensor.
