You need distance measurement for hydraulic cylinders suppliers up to 3000 mm, a simple limit switch is not good enough and a magnetostrive system is to expensive ?

Then check out the new BDS2 Sensor form Barksdale. The sensor with a resolution of 4 mm offers new possibilities within the mobile hydraulics market, i.e. distance measurement for hydraulic cylinders or level control. The BDS2 is designed for use in tough environmental conditions, EMC-safe and with good shock and vibration resistance.

The measuring principle is based on hermetically sealed reedswitches actuated with a magnet. The actuation is 100 % wear-free and contact-less and is achieved either with position magnets or a simple float.

The sensor stem is stainless steel and the electronics encapsulated and integrated into the stainless steel sensor head with connection via cable for ease of system integration.
BDS2 may be used with the Barksdale UAS3-V3 indicator to provide visual indication of position or level

 BDS2 is available either with position magnet or various floats for level measurement.
 Maximum length of sensor 3000 mm
 The output signal of 4-20mA is factory calibrated on the sensor length.
 Manufacturer of power supply : 10 to 30 VDC
 Operating temperature: -20°C to +80°C.
 May be mounted in any position.
