Convir non-contact temperature switches

The new Convir DL series from Calex Electronics is a range of high temperature fast response non-contact infrared temperature switches, designed for detecting hot metal or molten glass items

The new Convir DL series from Calex Electronics is a range of high temperature fast response non-contact infrared temperature switches.

They are designed for use in the detection of hot metal parts, or as part of a counting or positioning process.

Typical applications include billet positioning in steel forging and rolling, positioning and counting of gobs in glass production, and monitoring the opening and closing of furnace and oven doors.

Two models are available in this series, the DL-14 has a temperature range of 400C to 1400C and the DL-15 has a range of 700C to 1500C.

They measure with an accuracy of up to 0.75% of reading, and offer an outstanding repeatability of better than 0.3%.

Both models have an ultra fast response time of just 1 ms and a transistor output of 20 V DC at a maximum of 30 mA.

The switching temperature of the DL series can be easily adjusted via a potentiometer at the rear of the housing.

Each model has a narrow 66:1 field of view, allowing small or distant targets to be monitored.

An LED pilot light is also provided on all models to help ensure they are accurately aligned with their target.

The DL series are made of stainless steel and are sealed to IP65.

They can operate in ambient temperatures up to 50C without the need for cooling, and in higher temperatures with optional air and water-cooled housings.
