Single Point RF Level Switch

Models: 651, 681
Ranges: 0 to 4000 psi, 0 to 275 bar; -40° to 400°F, -40° to 204°C
Certifications: Unit: IECEx, CSA, FM, INMETRO, RTN

The 651 single point RF level switch provides basic, single-point switching for use as an alarm or level indication. It’s virtually immune to process coatings on the probe, making it a useful solution for many tough level applications. With no moving parts, the 651 single point switch with self test is well-suited for applications where other technologies struggle with accuracy.

Low cost
Single-point switch for alarm applications
Pressure from vacuum to 4000 psi, temperature from -40°F to 400°F
Relay and current shift (8/16mA) output available
A variety of probe configurations are available to meet most application conditions

SOR RF level switches are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. They are designed to measure point level readings. Point level switches provide output when a specific level measurement is reached.

Low maintenance – high performance

No moving parts and can operate effectively through a wide range of temperatures, pressures, vapor gas mixtures, and process conditions
Not affected by changes in pressure, temperature, specific gravity, vapor or density
Easy calibration
Continuous self-check mechanism for peace of mind
