No-cal Compact Point Level Switch For Liquids

PRISMATIC..... Series instruments are suitable for the detection of liquid level in small vessels where space is limited. Level detection is unaffected by electrical and physical parameters of the media such as conductivity, dielectric constant, density, viscosity, air bubbles, color and refractive index. It is very compact and fits in constrained spaces. It is unaffected by vapors and can be easily removed, cleaned and re-installed. It has no moving parts and can be used for the detection of level in chemical and Pharmaceutical industries, food processing, beverages, breweries, hydraulic fluids, oils, water and aqueous media.

Salient Features :
Compact design, no moving parts.
No calibration required
Selectable Fail-Safe mode for High or Low level Alarm
Built in level status, Alarm and Normal indicators.
Pulsed light operation for high ambient light immunity
Open Collector PNP Transistor output for connecting to PLC or external relay
Variety of models available to cater to different applications

Operating principle :

An infrared emitter sends pulsed light into the prism. When the prism is not covered by the media, the light undergoes a total internal reflection and the returning beam is detected by the Photo Detector. When the Prism gets covered by the media the light is dispersed and only a weak beam returns to the Photo Detector. The change in the received intensity is processed by the electronics to signal an Alarm.
