WTS-AM-3 Wireless 4-20 mA Transmitter Module
Wireless 4-20 mA Transmitter Module
The WTS-AM-3 transmitter module connects to 4-20 mA conditioned sensors such as pressure, %RH, inclinometer, accelerometer, depth, vibration, temperature and flow. It forms part of the WTS modular telemetry system. The data transmitted by the WTS-AM-3 can be received by multiple WTS receivers that include displays, handheld readers, analog outputs, relay modules and computer interfaces.
WTS transmitters have been designed for battery operation and support an ultra low-power sleep mode whilst offering class leading wireless coverage and range. Configurable transmission rates from once per day to 200 per second cope with a wide range of measurement and monitoring applications. A choice of enclosures enabling battery connection, field connectivity and environmental sealing up to IP67 ensure these modules provide a flexible solution to your wireless sensor requirements.
The WTS-AM-3 provides 5 V excitation to power external sensors. This transmitter provides up to nine point linearization giving quality measurements from a wide range of sensors.

Power
Attach power supply wiring to the module as shown below:
This module is not reverse polarity protected!
The maximum voltage is 3.6 V!
For battery information please refer to Appendix D – Battery Selection in the WTS Telemetry User Manual.
Sensor
Voltage input connected as follows:
WTS-AM-3-D
Power
Power can be supplied by fitting two D cell alkaline 1.5 V batteries or the module can be supplied from an external 5 Vdc to 18 Vdc source.
In both cases you need to fit the JP1 power jumper to supply power to the transmitter module.
When powered from the external DC source the LED will illuminate.
Sensor
The strain gauge input is connected to the module via a 2 part screw terminal block.

Shield Connections (All Enclosures)
We recommend the following rules to determine whether there should be a connection between the transmitter module shield and the sensor chassis or cable:
- If the sensor is remote to the transmitter module and the screen of the signal cable is NOT connected to the sensor chassis then the cable screen should be connected to the transmitter module shield connection.
- If the sensor is remote to the transmitter module and the screen of the signal cable IS connected to the sensor chassis then the cable screen should be NOT connected to the transmitter module shield connection.
- If the transmitter module is integral to the sensor or mounted very close and the module is mounted on a metal chassis then the answer to whether the transmitter module shield connection should be connected to the metal chassis is a matter of experimentation. This connection must be as short as possible. The T24 Toolkit can be used to chart the signal levels and tests should be undertaken to determine whether there is a better radio signal with or without the shield/chassis connection. The quality of the measured reading should also be looked at. In cases where the shield/chassis connection makes no difference to the radio signal or the reading quality then the connection should be made.
