Temperature Detectors

The EV487 and EV488 temperature detectors are suitable to detect the temperature in hazardous sites. Remarkable features are: linearity and accuracy of the calibration that allows a perfect interchangeability. If they are connected with appropriate electronic devices, these detectors give precise indications of the detected temperature or possible hazardous situations.

Advantages

• long life
• good stability
• hight sensibility
• linear output signal
• rapid response
• hight chemical resistance
• good mechanical resistance
