Description

The T24-VA 0-10Vdc wireless voltage transmitter module enables high accuracy wireless measurement of signals from voltage output sensors such as pressure transducers, LVDT displacement sensors, level/depth sensors and torque transducers.

Transmission ranges of up to 600 metres are possible using the internal antenna, while the use of an external antenna increases the wireless voltage transmitter operating range up to 800 metres.

The T24-VA requires a power supply of just 3Vdc to operate which is typically provided by 2x ‘AA’ batteries and provides a highly stable, high resolution signal that can be received by any of the T24 range of 2.4GHz telemetry instrumentation.

Output rates of up to 200 readings/second are possible at a noise-free resolution of 1 in 7000, increasing to 1 in 15,000 at a reduced output rate of 1 reading/second or less.

The compact T24-VA voltage input wireless telemetry acquisition module can be integrated into load cells and other sensors if sufficient space is available.  Alternatively, it can be mounted into either the T24-ACM(2x ‘D’ size batteries) or T24-ACMi (2x ‘AA’ size batteries) battery-powered modules to complete your wireless sensor.

T24 Transmitter Module Battery Life Calculator

Select the required module and enter the chosen parameters including the battery type. Click 'Calculate' and the noise free resolution and the expected battery life will be displayed.

T24 Device
Select your module.
Tx Interval (ms)
Enter the transmission interval in milliseconds. The default is 333mS which is three transmissions per second.
Sample Time (ms)
Enter the sample time in milliseconds. Increasing the sample time will improve the noise free resolution at the expense of battery life.
Load Cell Impedance (Ohms)
Enter the loadcell impedance in ohms or the current drawn by any external sensor in the case of a T24-VA or T24-IA.
Usage Per Day (hours)
What is the estimated number of hours per day that the device is likely to be awake. Remember that when not in use the modules enter a very low current deep sleep mode.
Battery
Selecting a common battery type here will populate the usable battery capacity below.
Usable Battery Capacity (Ah)
Enter the usable battery capacity. This may not necessarily be the published capacity.
Startup Time (ms)
This optional feature allows time for an external sensor to start up. This is not required for load cells.
Low Power Mode
Select this to enable the module to save power between transmissions. If the battery life looks too short check here to see if Low Power Mode is selected. This is not available for T24-SAf modules.
