NEW: electronic speed sensor by Schenck Process

Electronic rotational speed change sensor

The Rocon is a self-contained sensor is employed to sense blades on a target rotor mounted on the driven shaft. The unit operates on a digital principle, the response time being inversely proportional to speed, i.e. the higher the speed the shorter the response time. Switching occurs when the frequency of the blades passing the sensor corresponds to the threshold frequency. On dropping below the threshold the sensor de-activates.

Standard Units

Allows a machine to ‘run up to speed’. If normal running speed is not achieved within 10 seconds the sensor switching current is interrupted. Pre-set to activate at the min speed of 0.8 rev/min. Adjustable on site. (On request, units can be supplied to activate at a specified speed.)

DSEAR/ATEX

The RoCon® Series 6 complies fully with the Dangerous Substances and Explosive Atmospheres Regulations 2002 and the requirements of Category 2 & 3 Equipment. It is suitable for use in Zone 21 & 22 conditions.
