How TrustSens works

(1) Regulated industry
Measuring points in the life sciences and food & beverage industries often have to be dismantled and reassembled several times a year in order to be calibrated. This is time-consuming and costly, in particular for large plants.

(3) Physical phenomenon
The sensor takes advantage of the so-called Curie temperature: a constant value which, once attained, abruptly changes the characteristics of a material. The Curie value can be precisely determined for every material.

(5) Minimal effort
Human intervention is only necessary if the TrustSens sensors report a malfunction. Calibration certificates can be provided automatically via asset management software such as Endess+Hauser’s FieldCare.

(2) Sense-it-yourself
With TrustSens this is a thing of the past: it is the first sensor that can carry out its own traceable calibration – continuously and on-line. This reduces the risk of unrecognized measuring errors down to a minimum.

(4) Built-in reference
A special reference (master) sensor supervises the primary temperature sensor. A calibration of the primary sensor occurs each time the Curie temperature of the reference sensor falls short.

10 years of research and development back up TrustSens. The Endress+Hauser life sciences network initiated the breakthrough technology. Customers and partners from the world of science were closely involved.

850.000 euros is the amount a plant operator can save with TrustSens over a period of five years if 1,000 temperature sensors have to be recalibrated twice a year. By this sample calculation, the extra investment pays off after only the second calibration.

Conventional recalibration

Disassembly Depending on the industry and criticality of the measuring point, a sensor must be calibrated on a biannual to weekly basis. The process has to be stopped.

Calibration Qualified staff have to disassemble the sensor and calibrate it in a mobile block calibrator with a traceable reference (master).

Documentation Authorities and customers alike demand valid certificates. These have to be manually prepared by the calibration specialist before being filed by the customer.

Reassembly, cleaning Following the reassembly of the sensors the plant often requires sterilization. Only now can production begin again.

Recalibration with TrustSens

Self-monitoring A special reference sensor – the master – allows for a one-point calibration of the primary temperature sensor in the ongoing process.

Reference measurement The master utilizes the Curie temperature principle. Falling short of this value – such as after cleaning with steam – initiates calibration.

Operation The process is not interrupted; the system is not opened up. Staff need only intervene if TrustSens reports a malfunction.

Documentation The calibration data is saved in the field device. With Endress+Hauser’s FieldCare software, a valid calibration certificate is always available.
