CALIBRATION SERVICES

REFERENCE TEMPERATURE SENSORS

Whether you need working standards or reference standards, we possess high-performance equipment allowing us to manufacture specific temperature reference standards for calibration by comparison of your resistance sensors and thermocouples.

Need advice? Our metrology specialists are there to guide you, step by step.

Working standards 
Used in workshops and laboratories, reference sensors allow first-level calibration. They must be recalibrated regularly against a reference standard.

SENSOR WITH IN-SITU CALIBRATION

Save energy: choose sensors with in-situ calibration!

capteur in situ pyrocontroleIf you use sensors with in-situ calibration, it is possible to check the temperature without removing the sensor and without halting the process. The principle is simple: on the temperature assembly, a space is provided to insert a standard sensor for in-situ calibration by comparison. This helps to save energy while boosting productivity and quality.

Applications
Patented method (patent no. 0213616) which can be used for all types of temperature measurement devices, whether they involve thermocouples or platinum resistance probes.
This type of sensor is very widely ised in industrial furnaces and petrochemicals.

> Advantages of sensors with in-situ calibration:
- Avoids overheating: saves energy
_ Saves time: temperature calibration performed directly on site
- Not necessary to remove the sensor
- Not necessary to shut down the process
- Calibration frequency as you require.

FIXED-POINT CELLS

High-precision calibration

Calibrating a sensor using fixed-point cells involves placing it in an environment whose constant, uniform temperature is defined by the thermodynamic equilibrium between different phases of a pure substance.  This solution makes the calibration particularly precise. Before delivery, each fixed-point cell is checked in the French national metrology and test laboratory laboratory (LNE).

> Advantage of the method with fixed-point cells:
_ Provides high-precision calibration at a known temperature
_ No reference sensor, which may be subject to drift over time
It should be remembered that this is the method used to define the International Temperature Scale (ITS-90).

According to your requirements, our metrology specialists can adevise you to help you choose the right cell.
