MHF15 Optical Point Level Switch A range of easy to install level sensors requiring no calibration and suitable for installation in confined or difficult to access areas. SICK's MFH15 series of optical level switches are robust and simple in construction and manufactured from stainless steel and polysulfone with a casing rated to IP 67. Optical Level sensors operate using a LED light and the principle of refraction. The level sensor emits a beam of light from the LED which is directed via a prism at the tip of the sensor to a receiver unit. When the level detectors prism is immersed in liquid the emitted light is lost to the surrounding liquid and triggers a response.Ideally suited to level monitoring of fluids and water based media and suitable for applications such as pipe leak detection and level detection in industrial, pharmaceutical and food manufacturing systems and dry running protection. No calibration required IP 67, IP 69K rated enclosure 2 ms response time 250 Hz switching frequency Choice of PNP or NPN output Stainless steel casing M12 4 pin connection FDA Compliant Note These sensors cannot detect low density foams. Use with high density foams may lead to incorrect operation.

SITRANS LU150/LU180 The SITRANS LU150 and LU180 series from Siemens are short-range, non-contacting ultrasonic level measurement transmitters. They have been designed for liquid applications, mainly in the environmental and energy management industries. The transmitters are ideal for the continuous level measurement of liquids and slurries in open or closed vessels. The transmitter benefits from a fully encapsulated PVDF sensor which is resistant to corrosion, chemicals and extreme shock. Due to having only two wires, the unit is simple to install and with its two-button interface, easy-to-use. There are many mounting possibilities as there are four connections to choose from including the 4"" Tri-clamp designed for easy removal. The level readings are reliably supplied by Sonic Intelligence Echo which processes Siemens refined algorithms. These algorithms provide an accurate, unique and effective transmitter exclusively from Siemens. Features and Benefits Easy to install/program/maintain Accurate and reliable Tri-clamp process connection available Sonic Intelligence Echo processing delivers accurate measurement Integral temperature compensation IP68 rated for submersible applications Intrinsically safe rated for hazardous locations Product Application Information Chemical storage vessels Filter beds Mud pits Liquid storage vessels Food applications

191-9471, RS PRO

Compact, vertically mounted devices with a single switch point. Mounting is either from the top or bottom of a tank from the inside, so requires access to the inside of the tank. Typical applications include vending machines, printing systems and chemical dosing equipment. Available with M12 x 1.75 or 1/8"NPT mounting threads. The switch action may be reversed by removing the float, inverting it, then refitting to the stem. 25VA switching capacity M12 or 1/8" NPT mounting threads Compact design Manufactured from PPS

Available with either flying leads or M12 socket for electrical connection. Cable sets with M12 plugs are also available. They are manufactured in a variety of plastics, with a choice of gasket materials, to suit most commonly used liquids. The switch action may be reversed by mounting the device with the float able to move upwards away from the body, instead of the more normal downwards direction. This float switch series is designed for fitting through a tank wall from the outside, where access to the inside for fitting is not possible. These devices are particularly suitable for detecting low levels of liquids in the bottom of tanks and containers, and for lower SG liquids. Typical applications include vending machines, commercial dishwashers and auxiliary tanks on vehicles. Compact design Very low level sensing Suitable for low specific gravity liquids Flying lead or M12 plug connection Available in Nylon, Polypropylene or PPS Compression seal fitting
