WiSensys® Wireless Sensor WS-DLXm

Overview
WS-DLXm measures process signals and transmits data to the base station. Sensing is done using any available sensor that has 0 – 1 V DC output. This al ows connecting many commercial y available sensors that monitor a wide variety of measurement parameters such as flow, level, pressure etc. Sensor values are sent by the receiving base station to: - WiSensys® PC software SensorGraph via a serial interface or to
- Wisensys® internet Websensys via TCP/IP or GPRS
- Or to a data logger, PLC, automation system via RS485/422 - Or in the case the base station is equipped with an analog output module the values
can be forwarded as 0 -10 V DC or 4-20 mA signals (max 4 outputs) to a data logger or The intervals for sensing and transmission are set at instal ation time. Values can be changed WS-DLXm has a unique identity and a network ID. Transmitted data is encrypted thereby avoiding other wireless systems or receivers to receive the data. Optional y the fol owing values can be Trip values are used to signal an alarm condition to the base station. The sensor can local y store up to 10.000 measurements in non-volatile memory. This storage is used when a connection to the base station is not available to ensure that measurements are not lost. Whenever the sensor and base station are in range again, the data is transmitted to the base The distance between sensor and base station can be up to 1000 meters in case of free line-of- sight. Characteristic in-building range values are between 50 and 80 meters.
Sensor versions
Based on the power supply of the sensor we distinguish the fol owing situations: - Order the WS-DLXm having a 3.6V Lithium battery. With default settings of sensing
and transmission intervals, the lifetime of the battery is 3 years. - Power from the electrical grid is available; order the WS-DLXm-extp; the sensor
element is powered via this unit or via an own power supply
Features
• Ability to store 10.000 measurements; overwrites oldest data when ful • Attractive ABS enclosure; other enclosures upon request • Wal mounting possibilities included in enclosure • Range: 1000m with free line-of-sight • Easy to add sensors to operational system www.wisensys.com
