The perfect solution for monitoring levels in sumps, drains and sewers, in particular those where there is high humidity or high level inlets that create splashing that could impact on the suitability of BDT types of level sensors.
Utilising a industry standard NAMUR DIN 19234 interface the unit is fully compatible with high quality floats such the Pepperal+Fuchs LFT1 family.
The transmitter is available as standard to ATEX Category 3, Zone 2 and for operation on 434MHz and 869MHz WBFM in line with the essential requirements of the Radio Equipment Directive RED 2014/53/EU.
Operating at a transmit rate of once every 2.5 seconds, this sealed to life to beyond IP68 (fully encapsulated) the deign can achieve a battery life of over 10-years. Further with its transmit duty cycle of less than 0.4% the design is fully complaint with Article 3.2 of the RED and fits comfortably within ERC-Recommendation 70-03 for spectrum occupancy.
Utilising the RDNET™ ultra-lean radio protocol, the unit is fully compatible with the existing RDN1000™ booster, receivers, repeaters and Gateways and can be supplied to emulate the characteristics of the highly successful BDT or FDT sewer monitors.
The FST is idea substitute for BDTs in applications of high humidity, open rain or where and operational hysteresis is desirable required using a single device. The cable type is PVC as standard making the unit idea for Water and Wastewater applications.
Cable length is 5m as standard and can be suppled shorter if required.
The FST can be used in conjunction with the Sentinel or Gateways receivers and data can be ported via Data Concentrators over TETRA, LAN or even Satellite Networks.
