		LS-541 - Float Switch
		DESCRIPTION The LS-541 is intended to monitor the liquid level in a tank or vessel and provides a switched output for local alarm, pump or valve control. The differential between switching is equivalent to approximately 15mm. The unit mounts into 1” BSPT female boss. Access is not required to the inside of the tank.


		LS-CAP - Capacitance Level Sensors
		DESCRIPTION TThese sensors are designed for level measurement in tanks or sumps providing a 4-20mA output relating to the level of fluid in the tank. The LS-CAP1 is suitable for conducting liquids such as water whilst the LS-CAP2 is designed for use with clean, low viscosity non-conducting liquids such as oil. Both types consist of two concentric elements, an inner probe and an outer tube. Fluid rises in the cavity between the two concentric elements and the changes in capacitance are transposed into an analogue 4-20mA output signal FEATURES • Suitable for a wide range of media • Easy in-situ range adjustment • 4-20mA output • No moving parts • Unaffected by pressure or vacuum


		LS-FL - Liquid Level Float Switches
		DESCRIPTION The LS-FL series is a range of Level Switches suitable for single or multi-level applications where access is only available from the top surface or where multiple level sensing is desired from a single penetration. Units consist of a float, which is suspended from a weighted cable. As the liquid level changes, the float follows the surface level, at the same time tilting due to its weighted restraint. Inside the float are a number of micro switches which trigger as the float tips.


		LS-AFS - Automatic Float Switch
		DESCRIPTION The LS-AFS is designed for simple reliable water level control. The float switch can be used to control a pump for either tank filling or tank emptying (a high or low level cut-out). It is easily achieved by positioning the float stops on the cord. The electrical connections are easily made inside the housing, via the terminal strip. Two M20 cable glands are provided for use with suitable conduit. FEATURES • Reliable • Easy to install • Easy to adjust • Simple wiring


		LS-S - Side Mounting Liquid Level Switches
		DESCRIPTION A range of Level Switches designed for high and low liquid level detection in tanks and vessels. Units consist of a lever arm reed switch assembly and a tank fixing assembly. Type 1 switches fit from the inside of the tank and tighten on to a back nut whilst the type 2 switches mount from the outside into a tapered boss. FEATURES • Low cost solution • Stainless steel version suitable for a wide range of fluids


		LS-TM - Top Mounting Liquid Level Switch
		DESCRIPTION The LS-TM is an easy to install Top Mounting Level Switch, and has a reversible float so that it can be used for either high or low level alarms. The float is suspended from a 5 metre PVC cable with a polyethylene weight and is fully submersible and adjustable. FEATURES • Low cost • Easy to install • Reliable switching


		LS-MC - Ultrasonic Level Transmitter
		DESCRIPTION The LS-MC is a Ultrasonic Level Transmitter for measurement of liquids in tanks or sumps. The 4-20mA output represents the distance between the surface of the liquid being detected and the sensor. The LS-MC has an integral LCD display, three push buttons under the lid for security, and just eight parameters to set making it one of the simplest ultrasonic level transmitters to calibrate and use. FEATURES • 2-wire loop powered • IP67 housing • 12 to 30Vdc power supply • Fast speed of response, as much as 10m per minute • Locking nut supplied
