The Alfa Laval Potentiometric level transmitter is designed specifically for small tanks containing highly viscous and pasty products, such as ketchup, honey and toothpaste.
All wetted parts are made of AISI 316L stainless steel and PEEK, and designed to withstand process temperatures between -20 and +140°C. Because these 3-A certifed transmitters can withstand high temperatures, they are well suited for use in Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) processes.
The Alfa Laval Potentiometric level transmitters are easily mounted in top, bottom or angled position. Regardless of position, advanced integrated electronics enable automatic recognition of the transmitter output signal thus ensuring reading accuracy.
Operating principleThe Potentiometric level transmitter can be used with all media that have a conductivity of at least 50 ?S/cm. The low resistive measuring probe on the transmitter conducts a high frequency current through the medium in the tank. The voltage applied between the probe and the tank wall is then measured. The output voltage is proportional to the tank filling level. The measurement is unaffected by temperature and adhesive media. |
Application
The Alfa Laval potentiometric level transmitter is designed to fulfil the demands in Sanitary and pharmaceutical production. The main features are:
Standard range
The Alfa Laval potentiometric level transmitter is ideal for measurements in small vessels with tough, pasty or strong adhesive media, such as ketchup, honey, and toothpaste. The integrated electronics provide a 4-20 mA output signal and has incorporated automatic recognition of top or bottom mounting position, Even angled installation is possible. Due to the high temperature limit the Alfa Laval potentiometric level transmitter is well suitable for CIP and SIP processes.
Working principle
The Alfa Laval potentiometric level transmitter utilizes the potentiometric measurement principle and can be used in all medias that have a minimum conductivity of 50 ?S/cm. From the low resistive measuring rod a high frequent current is fed through the medium to the tank wall. The voltage between the rod and the tank wall is measured. This output voltage is proportional to the tank filling level. The measurement is unaffected by temperature and adhesive media.
Electrical data
The integrated electronics features as standard automatic top or bottom mounting recognition, and LED´s for local readout of level. Adjustment of measuring range is done via two push buttons and LED‘s in field housing.

Food and beverage, Home and Personal care
Alfa Laval Level switches are hygienic measuring devices that are especially suitable for detecting liquid levels in small process tanks used in brewery, food and beverage and personal care industries. This includes low-viscosity liquids, such as water and beer, as well as high-viscosity liquids and pastes, such as honey, yoghurt and toothpaste.
All wetted parts are made of AISI 316L stainless steel and PEEK, and designed to withstand process temperatures between -20 and +140°C. Because these 3-A certified level switches can withstand high temperatures, they are well suited for use in Cleaning-in-Place (CIP) and Sterilization-in-Place (SIP) processes.
Level switches enhance process reliability by delivering fast, accurate indication of the liquid levels. Integrated electronics provide a digital logic signal and incorporate automatic compensation for foam and bubbles as well as viscous, sticky media.
Operating principleTo measure the liquid level, the level switch employs a high frequency sweep signal, which is emitted from the sensor tip into the tank. The media act as a virtual capacitor that, together with a coil in the sensor head, forms a circuit creating the switch point signal. This virtual capacity depends upon the dielectric value of the media, which is well defined for most media. |
