Wireless Load Sensor

Wireless Load Sensor

The wireless Load Sensor is a strain gauge based stainless steel tension type sensor. It has the capability of wirelessly transmitting its data to one of our compatible readouts and displays or recording its data locally. Its inbuilt 32MBit memory can hold up to 280 hours of data which can then be downloaded to a PC via its USB cable. The Load Sensor transmits using the worldwide licence free frequency of 2.4GHz on two built in antennas.
Wireless Load Sensor (LoadSense)

The Load Sensor is used with our HandHeld Receiver which can read several devices at the same time, (see data sheet WLS3626R for more details), and/or our stand alone Receiver Interface which is used to output the data via RS232/RS422, (see data sheet WLS3627R for more details)

Handheld Receiver

Handheld Receiver

The wireless receiver is used in conjunction with the wireless Load Sensor. It provides the user with an easy way to receive and output data from the Load Sensor. Enclosed in a hardwearing aluminium box the receiver is suitable to be installed into environments where it may be subjected to harsh conditions.

The receiver is easy to install as it only requires DC power to be supplied to the unit. An SMA connector allows the use of an external antenna.

The wireless LoadSense HandHeld Receiver Display is used in conjunction with the wireless Load Sensor. It provides the user with an easy way to receive and view data from the Load Sensor.

Up to 9 Load Sensors can be selected from the HandHeld Receiver and individually displayed. These Load Sensors can be named by plugging the Load Sensor into a PC via USB and using the Load Sensor software.
They can then be easily distinguished on the display, which will show the current name of the Load Sensor being read.

The display shows the name of the current Load Sensor, the load, battery status of readout and Load Sensor and signal strength. By using the menu tree on the readout the user can select which Load Sensor to read, what units to be displayed, tare the data, display peak value and many more functions.

A 9 way D connector is provided to output data via RS232 / RS422 and a USB mini B to charge the battery and output data to a PC.
Key Benefits:

- Reads multiple Load Sensors
- Receives data up to a distance of 100m
- Receives data at 10 times a second
- Connect to PC via USB for user setup
- Output data via RS232 / RS422 / USB
- Ruggedized rubber case with back stand
- Long life rechargeable battery powered
Load Sensor Cabin Display

Load Sensor Cabin Display

The LoadSense Cabin Display is a small, lightweight, cabin / window mounted unit which is used in conjunction with our LoadSense Wireless Load Sensors to display the reading from the load sensor. Our range of Load Sensors up to 25 tonnes are shown in datasheet WLS3625R.

Using the 2.4GHz licence free band to receive the Load Sensor signal, it can display the load value in several views which are user selectable. It also allows the user to tare off any equipment weight to display just the load value of the cargo.

The system can operate from its rechargeable battery and does not need to be hard wired, enabling the equipment to be easily transferred between installations. The display can be operated and charged from a 28V supply

Receiver Interface

Receiver Interface

The wireless receiver is used in conjunction with the wireless Load Sensor. It provides the user with an easy way to receive and output data from the Load Sensor. Enclosed in a hardwearing aluminium box the receiver is suitable to be installed into environments where it may be subjected to harsh conditions.

The receiver is easy to install as it only requires DC power to be supplied to the unit. An SMA connector allows the use of an external antenna.

The receiver outputs a string of data from the Load Sensor which includes: Serial number, full scale, Load, Temperature, RSSI and battery voltage. The data is constantly outputted from the receiver straight from "power on" as long as the Load Sensor is in range. The output can be provided as either RS232, RS422, USB or Analog. This provides the functionality of being able to send the data over a longer distance if the receiver was to be in a remote location. The interface is suitable for applications where no user interaction is needed and data is fed into a data logger or remote display. An internal memory with real time clock is available for stand alone applications which may be interrogated from a PC.

Key Benefits:
- Small Footprint (133mm x 67mm x 43.5mm)
- Receives data up to a distance of 100M
- Receives data at 10 times a second
- Minimal startup time
- Very simple installation
- Operates on 2.4GHz licence free band
