WSg WiRELESS 4-20MA SENSoR
INTRODUCTION
The WSG Wireless 4-20mA sensor provides remote monitoring of
4-20mA transducers without running wires. Contact data is sent from the
sensor to the WSG30 via an integrated 2.4GHz Wireless radio. The device
can transmit its signal up to 300’ indoors and even greater distances when
it has line-of-site. The WSG30 series of Wireless sensors also feature mesh
networking technology, which allows each sensor to be used as either a
Wireless sensor/router or as a low-power battery operated sensor (also
referred to as an end point). When used as a router, greater distances can
be realized because each sensor/router adds another 300’ of range to the
system. The sensor comes with 3 AA alkaline batteries which will power
the sensor for up to 2 years (end point mode). An optional plug-in power
supply is also available, in which case the batteries function as backup
power if main AC power fails (power supply required for router mode).
NOTE: Do not install the sensor in a dirty, humid, or corrosive
environment . Do not install the sensor in close proximity to other 2 .4GHz devices (WiFi, etc) .
Do not install the device inside of a metallic enclosure as this will impede it’s ability to Wirelessly
communicate with the WSG30 .

InstallatIon suMMary
1) Locate the sensor serial number on the small white label inside the sensor enclosure .
2) Enter the serial number into the WSG30 using the web page or keypad.
3) Mount the sensor.
4) Attach power supply if using as a router and install the batteries.
5) Watch the LCD or web page to confirm that the sensor has connected with the WSG30.
sensor regIstratIon
Before you power-up the sensor you must enter the serial number, located on the small white label
inside the sensor enclosure, into the WSG30. You can do this with the WSG30 web page or you can
enter it using the WSG30 keypad (see Sensor Registration earlier in this manual). Just be sure to jot
down the serial number before you attach the sensor to the wall.
Battery InForMatIon
The Wireless 4-20mA Sensor can be used with or without the internal 24VDC supply. When the
internal supply is used to power the transducer the device must be powered by an external power
supply, in which case the batteries are used as a backup in the event of a power failure. In this scenario
the batteries will last approximately 15 hours.
When the 4-20mA sensor is used with the internal 24VDC supply disabled, you can operate it on
battery power only. The approximate battery life is 2 years at a sampling frequency of 3 seconds.
