The ExTemp is an intrinsically safe pyrometer. It measures the temperature of surfaces in hazardous areas without contact, and provides a direct 4-20 mA output. It is certified to ATEX, IECEx and TIIS standards.
Explosion proof pyrometers typically have bulky, expensive housings, however because the ExTemp uses Intrinsic Safety as the method of protection, it is compact and low-cost.
The ExTemp’s IIC T4, IIIC T135°C, ATEX and IECEx rating makes it suitable for many applications in hazardous areas, including:

Reinforced membrane level indicator to be used to control normally the medium or minimum level of bulk solids in silos or vessels. The models are certificated for use in potentially explosive Dust atmospheres hazardous areas.
These controllers consist of a switch actuated by a membrane and it is recommended for dusty and powdery, granulated and grainy bulk goods like dust, flour, grain, sand, plastic, etc. with an easy flow and a bulk density from 0.3 to 2.5 t/m3.
The membrane must to be exposed to the material.
The movement of the switch is the result of the pressure exerted by the incoming bulk material against the membrane which forces the membrane to move backwards, reversing the position of the switch and the signal is used for example to control the transport system in the silo.
The models have a regulation system by a spring that allows the adjusment of the sensitivity. Tightening the regulation nut to reduce the sensitivity and increase the strain of the material to activate the microswitch. Clockwise insensitive.
The models are adjusted at their maximum sensitivity. It is necessary to ensure the proper pressure to the membrane that returns the membrane when there is no product covering it.
Drill holes in the silo or vessel and mount the indicator using screws, rods, fasteners or nuts M6 making sure of the easy flow of the material and ensure that the product leaves the membrane without product on it.
