The sensor is a magnetostrictive device consisting of a diaphragm,nickel tube,magnet,drive coil and pickup coil.
The sensor is a magnetostrictive device consisting of a diaphragm, nickel tube, magnet, drive coil and pickup coil.

If the diaphragm of the sensor is exposed to a liquid material, which offers greater mechanical resistance to the motion of the diaphragm, the transfer of energy to the pickup coil decreases. This results in a decrease in the signal feedback into the amplifier and a corresponding decrease in the signal available from the output of the amplifier.The decreased signal triggers a voltage sensitive network that controls the output relay.

A unique AUTO TEST self-checking circuit constantly verifies the integrity of the sensor circuits. The RED LED is illuminated when the product is absent at the sensor and the system is oscillating at approximately 40 kHz. If the amplitude or the frequency of the sensor circuits changes, the RED LED will go out. If the change of state occurs due to a level change, the relay will follow and change its state. However, if the change of state is due to a sensor failure or some other component failure, the relay will immediately transfer to the alarm condition. This foolproof feature protects the system for loss of power, major component failure or damaged sensor conditions.

 
Typical Uses
  • High Level Alarm or Control
  • Pump Control or Inlet Starvation Alarm
  • Flow/No Flow Indication
  • Low Level Alarm or Control
 
Function
  • Single Point Switch for On-Off Control of Liquids
 
Primary Areas of Application
  • Standard sensor is 347 SS Optional models are available in Carpenter 20, Hastelloy C or 316 SS
  • The SONAC®/120 is a reliable level control that will sense almost any liquid. Its failsafe features insure positive level control in critical processes. The non-intrusive features of its sensor permit its installation in extremely small vessels and pipes
  • Non-dedicated vessels-liquids
  • The device senses virtually any liquid and does not need adjustment when the density or dielectric constants are changed High temperature, high pressure service
  • The welded, all stainless steel sensor body is designed for service at temperatures to 4000°F (205°C) and pressures to 2000 psig Fluids with foam blankets
  • The control ignores foam to indicate the true liquid level Cryogenic fluids
  • Series 26 sensors are designed for service at fluid temperatures to -425°F (-255°C) Please inquire Precision level control requirements
  • Repeatability to 0.050 in. standard - Corrosion resistant sensors
