SITRANS AS100 Acoustic Sensor

Brand: Siemens AG
Request Information
Favorite

SITRANS AS100 is an acoustic sensor used for solids flow detection. SITRANS AS100 detects changes in high-frequency sound waves from equipment and materials in motion. It detects and reacts instantly to changes in solids flow to warn of blockages, product absence, or equipment failure such as burst filter bags.

The SITRANS AS100 acoustic sensor allows an operator to take early preventive action to avoid costly damage. Common applications include pellets, powders and most bulk solids in pipes, chutes, vibratory feeders, pneumatic conveyors or aerated gravity flow systems. Operating with a SITRANS CU02 control unit, the system detects conditions of high flow, low flow or no flow. 

It can be added to a control loop via a 4 to 20 mA output. Two relays are fully programmable and independent of each other and can be used to operate an alarm or control device. With no moving parts and a type 304 or 303 stainless steel enclosure sealed against dust and moisture, this non-invasive unit requires little or no maintenance. With a dual operating range, the sensor offers an exceptionally wide range of application capabilities.
