Echotel Model 961 Ultrasonic Level Switch

Brand: Magnetrol
Request Information
Echotel Model 961 Ultrasonic Level Switches use pulsed signal technology for superior performance in difficult process conditions, and to provide excellent immunity from sources of electrical noise interference. 

Extensive self-testing of the electronics and transducer make this advanced switch suitable for a wide variety of hygienic level switch applications. 

Model 961 is offered with either a 5-amp relay or a current shift electronics. 

The relay output electronics has a DPDT relay for level detection, and a SPDT malfunction relay. 

The current shift version indicates 8 mA during normal operation, 16 mA as a level alarm condition and a user-selectable 3.6 or 22 mA malfunction indication. 

The Model 961 switches are designed for the stringent requirements of hygienic applications. 

These switches are offered with a deep-drawn 304 stainless steel housing that is favorable to CIP and SIP procedures.

A 20 Ra surface finish is featured with hygienic Model 961 transducers. 

These transducers are available with 11/2" and 2" Tri-Clamp fittings and DN65 Varivent Type N flanges.
Features
  • Self-test technology provides unsurpassed reliability and testing of electronics, transducer, piezoelectric crystals, and electromagnetic noise.
  • 20 Ra surface finish with Tri-Clamp and Varivent fittings.
  • Adjustable time delay for turbulent aerated liquids.
  • Tip-sensitive transducer measures level within 1/4" of the vessel bottom.
  • Pulsed signal technology provides superior performance in difficult process conditions.
