The level switch UNS1000-BN18 made of brass is constructed for level and temperature monitoring of hydraulic tanks "Power Packs". Modern hydraulic reservoirs have a high specific output volume that can result in high oil temperatures under load. Level and temperature monitoring is a unrenounceable safety factor for the complete plant.

Q & A
UNS1000-BN18 Level and Temperature Monitoring Q & A
+ What is the UNS1000-BN18 switch used for?
This device is designed to monitor both fluid level and temperature in one unit—so you can detect when liquid in a tank or reservoir reaches a given level and when the temperature reaches a set point.
+ What are the operating conditions (temperature, pressure, density)?
The specs show: operating temperature from –10 °C to +90 °C (14 °F to 194 °F). Operating pressure up to 4 bar (400 kPa = 58 psi). Minimum fluid density ~0.64 g/cm3; depth of immersion at density = 1 is 15 ± 2 mm.
+ What process connections are available?
Typical connections include: male thread G 1/2″ DIN ISO 228-1 (which equals T?) and M20 × 1.5 DIN 13.
+ What electrical connection and ratings does it support?
Electrical connection options include plug M12 × 1 (4-pin, PA), plug DIN EN 175301-803-A (former DIN 43650) 4-pin (PA), or cable gland (PA). Electrical values: max. 24 V AC/DC, max. 1 A, max. 15 VA or W.
+ What materials are the main parts made of?
Materials: Bulkhead union = brass; Contact tube = brass; Float stopper = bronze; Float = foamed NBR.
