The explosion-proof temperature sensor model SMALL-Ex^® measuring Instruments are intrinsically safe temperature measuring instruments or as a special version for use as a thermo switch. They can be mounted and used in any position. They are designed for use in systems with fluid or gaseous medium as well as surfaces.

A patented variant of the SMALL-Ex® measuring instrument detects the temperature flank and compares this with the temperature gradients which are stored by the manufacturer, such as those at a belt start-up at the cheek of a conveyor belt. For this version, the level of the environmental temperature is irrelevant to the detection and does not affect the evaluation.

Products are certified by:

• ATEX
• IECEx
• EAC Ex
• MSHA
• SIL 2

Application Areas:
– For liquid and gaseous media
– Permanent/defined output signal
– High measuring accuracy
– Possible in flow measurement
– Equipment according to customer requirements
– Patented temperature evaluation
– For e.g. belt conveyor monitoring
