To avoid overfilling of stationary tanks and stationary-use tanks. Suitable for a wide range of inflammable and non-inflammable water-polluting liquids.
Description
Type-approved together with all level probes type series 76 and UFS 01 as part of an overfill prevention system. UFS 01 in a wall mounting housing consists of a transducer and a suitable level probe (to be ordered separately). The transducer contains all display elements and controls as well as all electronic components for signal processing and conversion of the level probe signal into a digital output signal. The level probe and the transducer are connected by means of a 2-wire signal cable. When the maximum permissible level is reached, UFS 01 triggers visual and audible alarms. The filling process is stopped. The transducer also features two output relays for connection of event reporting systems or additional alarm equipment. Ancillary control unit type 907-Z can be connected as an additional control unit to enable connection to a road tanker with filling system.

Application To avoid overfilling of stationary tanks and stationary-use tanks. Approved without list of substances for inflammable liquids (zone 0) and non-inflammable, water-polluting liquids (WHG/VAwS).
For connection to overfill prevention systems and leak alarm systems.
Description
Integrated visual and audible alarms indicate fault conditions. The audible alarm can be muted with the Acknowledge button. The visual alarm remains on until the probe is no longer in contact with the medium (e.g. "Tank full" signal) or until a fault condition is corrected. As soon as the visual alarm is switched off, the system resumes normal operation. Additional external alarm equipment can also be connected and acknowledged.
Type-approved together with the level probes LS 300 EU, LS 300 FU or LS 300 ESPU as part of an overfill prevention system. The transducer supplies the level probe via an intrinsically safe circuit, evaluates the change in resistance of the PTC thermistor, continuously checks the PTC thermistor operation and monitors the system (power failure, short circuit, line interruption, etc.). Negative results cause the overfill prevention system to respond. The overfill prevention system must be set up in such a way that the filling process is stopped or visual and audible alarms are triggered when the maximum permissible level is reached. The transducer must be installed outside of the hazardous area.

Level probe LS 300 EU
Level probe LS 300 FU
Approved part of an overfill prevention system according to WHG together with the LS 500 transducer – self-monitoring and with automatic corrosion monitoring. LS 300 EU consists of a height-adjustable probe tube made of stainless steel with a PTC thermistor sensor element at the lower end, a screw fitting and a brass junction box with integrated overvoltage protection. Standard length 500 mm, max. length 3,000 mm. The level probe can be used in inflammable liquids up to 3 bar overpressure (please specify higher pressure ranges when ordering).
LS 300 FU consists of a probe tube, welded to the flange (gas-tight) and can be installed in tanks with an overpressure of up to 3 bar. (Please specify higher pressures when ordering). A stainless steel version with a coating is available for use in containers with very corrosive media (acids).

Application
For use in electrically conductive and non-conductive liquids which are not viscous or adhesive: fuel oil, diesel fuel, emulsions, water, and media which are not corrosive.
Description
PTC thermistor type level controller with selectable functions: ■■ Level switch (1 probe) ■■ Level control for filling (2 probes) ■■ Level control for emptying (2 probes) Level switch with 1 probe: The relay switches in case of contact or loss of contact with the liquid. When the switch point is set, it must be observed that the PTC thermistor requires approx. 8 seconds to heat up depending on the ambient temperature. Level control for filling with 2 probes: Set internal switch to "fill". The relay energises after the min. probe has heated up. Relay de-energises when the max. probe comes into contact with the liquid. Level control for emptying with 2 probes: Set internal switch to "empty". Relay energises when max. probe has contact with the liquid. Relay deenergises when the min. probe loses contact with the liquid and heats up.
