System Devices
There are four devices in the Deeter Wireless Sensor product range:
• Base Station
• Wireless Sender
• LVCS-RF
• Wireless Router
The basic wireless sensor system comprises a Base Station and a single sensor
node, either a Sender or LVCS-RF. A Router may be added to the system to
improve communications reliability or to extend the wireless range. Up to four
Routers may be used in a single system.
The sensor nodes can accept a range of input devices to suit the application:
• Four switch inputs (Sender only)
• An analogue resistive input (Sender and LVCS-RF)
• A 4-to-20mA current-loop sensing input (Sender only)
Figure 3: Wireless Sender with 40-Series Float Switches and LVCS
Figure 3 illustrates a possible arrangement of inputs to a Sender with four Deeter 40Series Level Switches and a Deeter continuous level sensor.
The Base Station has a range of outputs to drive a wide variety of possible
devices:
• Four open-collector transistors
• 4-to-20mA current loop driver
• Serial communications output via RS232, RS485 or USB
(At present, serial communications is reserved for diagnostic
developments are expected to include data-logging features.)
