Temperature sensors

The two groups of temperature sensors most used in industrial electrical temperature measurement technology are:

• Resistance thermometers (RTD)
• Thermocouples (TC)

In the former, the measurement is based on the temperature-related change in the resistance of precious metals, while in the latter, thermal values are determined based on temperature differences between the measuring point and a reference point.

Resistance thermometers ensure a high level of reproducibility with the smallest deviations in the measurement results. Platinum sensors offer the best long-term stability. The chemical insensitivity of this precious metal reduces the risk of contamination through oxidation and other chemical influences, even at very low and very high temperatures.

Thermocouples can be used in a much wider temperature range than resistance thermometers. They are more robust and less sensitive to mechanical stress, and can be made extremely compact. Very small measurement points can also be integrated into the tightest of spaces. Another advantage of this type of sensor is its very good response time, which is usually shorter than that of resistance thermometers.

We will develop, produce and procure for you the following sensor models for temperature measurement:

• Resistance thermometers
• Thermocouples
• Sheathed thermocouples
• Slot sensors
• Infrared sensors

In order to ensure reliable temperature measurement, we will adapt the measurement technology to the installation location and the process involved. This means that you do not need to change your system or device design in any way. We will provide you with exactly the temperature sensor you need for your application.

We can offer the following specifications:

• Measurement ranges: -200 °C to +1800 °C
• Different housing designs
• Individual signal alignment
• Transmitter: 4 to 20 mA / 0 to 10 V

There are many different temperature sensor application areas. They are found in industrial production plants as well as in the energy industry, food production, heating and cooling systems, and shipbuilding. Other typical areas of application are in over-heating protection of microprocessors, household appliances, silos, fish farms, refrigerated transporters, and packaging plants, including greenhouses.

The most important fields of application for our products include industries such as:

• Pump and gear manufacturing
• Process control technology
• Measurement and control technology
• Railway technology
• Mechanical and plant engineering
• Roller technology

Construction work can be checked with Allmetra sensors, as can the hardening process of concrete. It is also easy to keep an eye on water temperatures in reservoirs and boreholes, and on the temperature of engines, generators, and turbines. Our temperature sensors meet all industrial requirements and international standards.
