The ABS float switch can be used in liquids for control operations by using the liquid level. It is suitable for use in sewage.
In the float switch a ball moves depending on the floating position and operates a high quality micro switch. The recessed rolling surface for the ball ensures trouble-free functioning even if the cable is twisted. In order to vary the switching differential it is possible to shorten or lengthen the cable fastening position. Minimum cable length 50 mm. That corresponds to a minimum switching differential of 100 mm. The switching height itself is set by raising or lowering the fixing point. Care should always be taken that the float switch can float upwards or downwards without any restriction. |

Limit Switch for detecting the level of liquid media
Application area: Refrigeration
OPG 04
Characteristics:
Compact construction Long service life
No moving parts Measuring accuracy ± 0,5 mm
Reasonable prices Simple to install
Electrical connection: cable connection or plug
Optical switch condition check via the LED
Mounting direction: any Output PNP
High reliability Pressure 4 MPa, optional also higher pressure
Adjustable sensitivity for any application Glass fused in the steel body (without sealing)
Operating Principle:
The electro-optic sensor contains an infrared LED and a light receiver. Light from the LED is directed into a prism which forms the tip of the sensor. With no liquid present, light from the LED is reflected within the prism to the receiver. When rising liquid immerses the prism, the light is refracted out into the liquid, leaving little or no light reach the receiver. Sensing this change, the receiver actuates electronic switching within the unit to operate an external alarm or control circuit.
Areas of Application:
The opto electronic level switches OPG04 are used for monitoring the level of liquids. Applications include plants in the refrigeration. |

Increasing demands for compliance with safety systems and overfill protection has mandated more reliable point level measurement. Echotel® Models 961 & 962 Ultrasonic Level Switches meet these demands with advanced transducer designs, extensive hazardous location approvals, and a new self-test technology.
Model 961 offers the ultimate solution to reliable single point liquid level measurement. This advanced switch uses 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 use in Safety Integrity Level (SIL) 2 loops.
Model 962 is a dual point switch that can be used as a level controller, or to control pumps in an auto fill or auto empty mode. The tip sensitive lower gap performs well in aerated or foamy liquids, and can measure to within 14" of the vessel bottom. The rigidity of the unique flow-through upper gap allows separations of 125" (318 cm) between the upper and lower gaps.
