Deeter Offers Wireless Level-Sensing SystemSeptember 8, 2009
The unit provides a link between level sensors and control systems or indicators and enables you to multiplex a number of sensor inputs, which allows you to control and indicate a whole range of sensors through one system.
TALLMADGE, OH /Marketwire/ -- The Deeter Wireless Sensor System is primarily designed to provide a wireless link between level sensors and control systems or indicators. The level sensors can be anything from a simple float switch (liquid level sensors or liquid level controls) to one of the Deeter continuous level sensors. In fact, the input can be from any sensor with a switched output or 4–20 mA current-loop output, as used for monitoring a vast range of sensors in many industrial or domestic control systems.
The Deeter Wireless Sensor System comprises four devices: two sensors, a repeater, and a base station. A minimum system would consist of one sensor and one base station, but can be expanded to include many sensors communicating with a base station. A repeater or several repeaters may be required in some installations to extend the radio signal range or improve communications reliability. The Deeter wireless system enables you to multiplex a number of sensor inputs, which allows you to control and indicate a whole range of sensors through one system.
Wireless Liquid Vertical Continuous Sensor (WLVCS)
The WLVCS is a continuous liquid level sensor that allows you to monitor liquid level over a certain length, using a ball float around a stem. The sensor is manufactured from 316L stainless steel. Standard sensing lengths are 250 mm, 500 mm, 750 mm, and 1 m (custom lengths are available on request). The radio circuit is housed in an IP67-rated alloy head, with an external antenna. The WLVCS is battery powered with a battery life greater than one year (subject to various conditions of use).
Wireless Level Sensor (WLS)
The WLS has a range of inputs, including inputs for 4 float switches, a Deeter continuous level sensor input, and a 4–20 mA current-loop. The WLS can be powered by an external power-supply, internal battery, or by the 4–20 mA current-loop circuit it is sensing. The WLS is housed in an IP65-rated ABS enclosure, with an external antenna and cable glands for power and signal inputs.
Wireless Sensor System Repeater (WSSR)
The WSSR is housed in an IP65-rated ABS enclosure, with an external antenna and a cable gland for power input from an external 5 V power supply.
Wireless Sensor System Base-Station (WSSB)
The WSSB is housed in an IP65-rated ABS enclosure, with a transparent lid. It has an external antenna and cable glands for power input and signal outputs. The full range of outputs is available, as described above. The WSSB has 3 push-button switches and a 2-line by 16-character LCD display, used to select a variety of options during initial setup. The display also provides information during normal operation and can be viewed through the transparent lid.
