Wireless Sensor Transmitter Line Tensiometer AcquisitionT24-LT1 OEM Module
SKU: T24-LT1 OEM Module
Description
The T24-LT1 is a versatile wireless OEM telemetry module designed for integration into running line tensiometer systems. When paired with appropriate mechanical hardware, it enables the real-time acquisition of cable tension, payout, and speed — critical parameters for dynamic load monitoring in industries such as marine, offshore, and rigging.
Developed on the proven foundation of the T24-SA strain acquisition module, the T24-LT1 provides high-accuracy load pin measurement and can be calibrated and scaled directly into engineering units such as kilograms or kilonewtons. This version requires integration with a suitable external antenna, which provides enhanced wireless range and signal integrity, particularly in challenging or obstructed environments.
The T24-LT1 was originally designed to work alongside the T24-HLT handheld display, providing a portable solution for viewing tension, payout, and line speed. While the T24-HLT remains available, it has been superseded by the T24-HK-S, a next-generation handheld display offering improved configurability, enhanced visualisation, and greater system flexibility. For all new installations, the T24-HK-S is recommended as the preferred display option.
Operating on the licence-free 2.4 GHz DSSS frequency band, the T24-LT1 offers reliable, interference-resistant wireless communication and is fully compatible with the complete T24 ecosystem, including base stations, analogue outputs, relay modules, and logging interfaces. Configuration, scaling, and calibration are performed wirelessly using the free T24 Toolkit software.

FAQ
| Q | Do the T24-LT1 and T24-HLT operate exclusively? |
| A | The T24-LT1 is compatible with other T24 receivers, but the T24-HLT has been specifically designed to allow the 3 measurements values transmitted by the T24-LT1. |
| Q | How is the T24-LT1 connected? |
| A | The T24-LT1 connects to a load pin and quadrature sensor. |
| Q | What wire configuration does the T24-LT1 require? |
| A | Strain gauge connection is 4 wire. |
| Q | What Frequency does the system operate on? |
| A | Licence free world wide 2.4GHz, although this frequency is used by other equipment, the T24 range has been tested with Bluetooth, Zigbee & WiFi devices without conflicts. |
| Q | What is the range of T24? |
| A | The T24-ACMm which has an integral antenna has a range of 400 metres direct line of sight. The T24-ACM / T24-ACMi uses a integrated PCB T24-ANTA antenna provides up to 800 metres range in ideal conditions. This range can be increased up to two times with the T24-AR (wireless range extender). |
