Temperature sensor has long-term
stability
Two different sensor elements that monitor each other while temperature sensing ensures that a developing sensor drift is immediately detected and reliably diagnosed.
With market leader ifm electronic's TAD series temperature sensors, regular calibration is no longer necessary The use of two different sensor elements which monitor each other in the process ensures that a developing sensor drift is immediately detected and reliably diagnosed

Sensor detects pump cavitation and stoppages
IFM Electronic's has developed a pump diagnostic pressure sensor that continuously monitors and detects cavitation, trapped air and blockages.
Cyclical calibration, which in the end provides no absolute security since the sensors used are only checked selectively, is thus not necessary.
Furthermore, if one element fails, the process continues with the second measuring element (backup function).
Via the diagnostic output of the sensor possible error states are directly transmitted to the higher-level controller.
A failure warning and switch-off threshold can simply be defined via the software.
Providing a standardised 4-20mA analogue signal enables processing in any common controller.
The sensor covers a temperature range of -10-150 deg C and is resistant to extremes of -25-170 deg C for a short time.
The evaluation accuracy is 0.2 K in the range of -10-100 deg C and 0.3 K for 100-150 deg C.
The integrated adapter thread enables hygienic connection to all common process adapters.
The shape of the probe and the high temperature range allow cleaning (CIP) and sterilisation when mounted (SIP).
The completely closed and welded high-grade stainless steel housing guarantees protection rating IP 69 K.
The selected design reduces the build-up of dirt and can be cleaned on all sides. Request a free brochure from IFM Electronic ...
