The TT-01 temperature transducer integrates the entire measurement electronics, including the calibration data. The calibration process integrated into the production process calibrates the entire measuring chain from the temperature sensor to the digital result. This offers high precision with easy handling and interchangeability.
Any Pt100 temperature sensor with a 3-5 mm connection cable can be connected to the TT-01 temperature transducer. We offer three different Pt100 designs with different cable lengths as a standard solution. The cable length depends on the application and the installation conditions.
For laser interferometry applications, the air temperature sensor must be placed close to the laser beam. A material sensor is usually attached to the machine bed, the test specimen or near the scales to be calibrated.
The TT-01 temperature transducer is connected to a T-input of the UW-3x environmental module of the electronic evaluation and supply unit of the interferometer or to the LCS precision climate measuring station. Use without one of these base stations is not possible.
for use with the TT-01 temperature transducer
Three different types of Pt100 temperature sensors are offered as standard.
1. Standard air sensor
The standard air sensor is based on an encapsulated Pt100 precision flat measuring resistor.
2. Dynamic air sensor
The dynamic air sensor is a wound Pt100 measuring resistor in a dynamically favorable needle shape. The design has been optimized with regard to the dynamic properties. The sensor can also be wet-calibrated, which potentially reduces the measurement uncertainty during calibration and makes it unproblematic to use in a humid environment.
This design is highly recommended for applications as a wavelength correction sensor for interferometers in a forced-air environment (e.g., actively air-conditioned measuring rooms).
3. Material temperature sensor
The material temperature sensor is a Pt100 precision flat measuring resistor in a small aluminum housing. The housing is equipped with magnets for attachment to ferromagnetic materials and a hole for screwing on.
These temperature sensors can be ordered as variants with the TT-01 temperature transducer or the WT-01 wireless temperature sensor.
Wired temperature sensors potentially enable simple operation and precise measurements. In some applications, however, they are rather impractical, e.g. at remote or difficult to access measuring points or for short-term measurement setups.
Our WT-01 wireless temperature sensors offer an ideal solution by forming a sensor network with up to 15 measuring points with a typical battery life of approx. one month.
The WT-01 wireless temperature sensor can be connected to any Pt100 temperature sensor with a 3 mm connection cable. As a standard solution, we offer three different Pt100 designs with cable lengths of 1 m (material sensor) and 1.5 m (air sensor). Customized lengths are available on request.
The wireless temperature sensor WT-01 requires a corresponding base station, which is integrated in the environmental module UW-34, the climate measuring station LCS-01 and the sensor box SB-32.
The sensor boxes combine precision air pressure transducers with a sensor for relative humidity. They can be connected to the environmental modules UW-32 to UW-34 and to the LCS climate measuring station.
The extraordinarily high accuracy of the air pressure measurement of ±50 Pa is achieved by a special calibration procedure during production.
The sensor boxes can be ordered with different cable lengths. As a rule, the standard connection length of 3 m is sufficient, as the sensor box must be positioned directly next to the interferometer. Positioning in the same room, for example at the height of the measuring section and as far away as possible from heat sources, is sufficient.
