Flow sensors handle rapid heat changes

An IFM Electronic product story
Edited by the Engineeringtalk editorial team Apr 2, 2003

Even when used in media where the temperature is changing as rapidly as 300K/min, the operating accuracy of the new SI2000 flow sensors from IFM Electronic is unaffected.

Even when used in media where the temperature is changing as rapidly as 300K/min, the operating accuracy of the new SI2000 flow sensors from IFM Electronic is unaffected, making them an ideal choice for plants which employ cleaning-in-place (CIP) technology.

IFM's new sensors also feature EHEDG and 3A certification for use in hygienic applications, and can be used with media at temperatures from -25 to +95C (+120C for a maximum of 1h), further increasing their appeal to users in the food, beverage and pharmaceutical industries.

Available with three different probe lengths, to ensure that optimum performance is achieved whatever the application, SI2000 flow sensors feature IFM's unique M0 mounting system.

This means that, with the aid of a simple adapter, the same sensor can be used with all common process fittings, including DIN, Varivent, clamp and IDF types.

Operating on the well proven and highly dependable calorimetric principle, all SI2000 flow sensors are designed for operation from nominal 24V DC supplies, and all have a single switching output.

When operating in liquid or gaseous media, the switching point can be set from 3 to 300cm/s, or from 200 to 2000cm/s, respectively.

IFM's SI2000 flow sensors incorporate a bargraph display, which displays both the switching point and the current flow rate.

Adjustment is by an integral microprocessor-based system which automatically optimises the operation of the sensor to suit the medium in which it is being used.
