Temperature

There are different types of temperature sensors available and all have different characteristics depending upon their actual application. There are two major types of sensors available: contact-less and contact. While the first ones use infrared radiation emitted from an object to determine its temperature, the latter sensors use thermal conduction to directly measure the temperature of solids, liquids or gases over a wide range of temperatures.

Thermocouples

A thermocouple is a junction between two different metals that produces a voltage related to a temperature difference of both junctions. Thermocouples are widely used for measurement and control applications in industry. They are robust but less

accurate than e.g. Pt resistors. Up to eight thermocouples of different types can be read out by our TMP01 Octal Thermocouple Monitor which features high accuracy, low noise and adaptive cold junction compensation.

Thermistors and RTDs

A thermistor is a type of resistor whose resistance significantly varies with temperature. Thermistors differ from resistance temperature detectors (RTD) in that the material used in a thermistor is a ceramic or polymer in most cases while RTDs use pure metals such as platinum. The TMP02 Quad RTD Monitor does not only allow to read out different high-accuracy Pt resistors, but also NTC thermistors and low temperature diodes for cryogenic applications.

TMP01 Octal Thermocouple Monitor

The TMP01 device is a versatile and easy-to-use temperature monitor. With eight inputs, it can be used with nearly any thermocouple type. The device was designed to meet the demands of scientific or industrial applications where the high temperature range, ultra-low noise and high resolution are important concerns. Standardized voltage-temperature curves are utilized for thermocouple B, C, D, E, G, J, K, M, N, P, R, S and T. Automatic software-based cold-junction compensation is automatically performed for highest precision.
The channels are multiplexed, amplified, conditioned and sampled by the 24-Bit delta-sigma A/D converter. This ensures maximum data acquisition rates of up to 3 kHz at lowest noise levels.
