Wireless Telemetry Systems 101

A wireless telemetry system enables the remote measurement and transmission of data from one location to another without the need for physical wired connections.  As technology continues to advance, wireless telemetry systems are becoming increasingly sophisticated, reliable, and secure, enabling them to be applied in a wide range of industries and use cases for test and measurement applications.

Interface offers a wide range of wireless telemetry products. Components in wireless telemetry systems typically include sensors, transducers, instrumentation, communication modules, transmitters, displays and printers.

The sensors are used to measure tension, compression, weight, torque, or any other measurable quantity. Interface utilizes proprietary strain gage sensor technologies. Transducers convert the analog signals from sensors into digital data that can be processed and transmitted to instrumentation.

Load cells are commonly used with wireless telemetry systems to measure and transmit data related to the force or weight applied to an object. The load cell converts the force exerted on it into an electrical signal, which can then be wirelessly transmitted to a remote monitoring system.

The most popular Interface wireless load cells are our WTS 1200 Standard Precision LowProfile® Wireless Load CellWTSTL Wireless Tension Link Load Cell, WTSLP Wireless Stainless Steel Load Pin and WTSSHK-D Wireless Crosby™ Load Shackle. Interface works with our customers to develop engineered-to-order wireless solutions by request.

The analog output from the load cell may require signal conditioning to ensure accuracy and compatibility with the wireless telemetry system. Signal conditioning can also be required for amplification, filtering, and analog-to-digital conversion to convert the analog signal into a digital format.

Wireless communications modules are responsible for transmitting the data over wireless channels. It can use various communication technologies like Wi-Fi and Bluetooth depending on the application’s requirements. The transmitter is responsible for wirelessly communicating the load data to the receiving end of the telemetry system.

There are various options for data collection. Data acquisition instrumentation is preferred in force measurement applications for the purposes of collecting vast amounts of the data from sensors and transducers and preparing it for transmission.

At the receiving end of the telemetry system, another wireless communication module receives the data from the load cell’s transmitter. Once the data is processed, it can be analyzed, logged, and displayed on a user interface, such as a computer dashboard or a mobile app. This allows operators, engineers, or users to monitor the load values in real-time and make informed decisions based on the data

Interface Wireless Telemetry System (WTS) Solutions

The Interface Wireless Telemetry System (WTS) offers flexibility by eliminating physical connections, making it easier to deploy sensors in remote or challenging environments. Wireless telemetry systems offer more flexibility in sensor placement and system configuration.

The absence of physical wires allows for easier repositioning or adding new sensors without significant infrastructure changes. This setup is particularly useful in scenarios where it is challenging or impractical to use wired connections, such as in large-scale industrial applications or when monitoring moving or rotating machinery.

Interface Crane Use Cases and Application Notes

Manufacturers and engineers of heavy equipment are rigorous about the design quality, performance and most importantly preserving safety. Having tools to test and monitor this type of equipment allows equipment producers and users to review performance at all stages, ultimately maintaining a safe working environment which is critical to any construction, transportation, or infrastructure project job site. That’s why Interface provides quality force measurement products for a host of industrial equipment machines to accurately measure force, load capacity, weight, tension and more.

Interface has been a long-time supplier of force and torque sensors along with instrumentation products for projects involving all types of cranes and lifting machines. We are frequently asked to provide crane force measurement solutions for applications used in hoisting, lifting, moving, and transporting heavy objects. These use cases range across all types of environments, from constructing high rises in metropolitan centers around the world to maritime industry users loading docks and lifting watercraft.

To outline how force measurement is used to monitor cranes, we developed a series of application notes explaining the components Interface provided to allow our customer to measure safety, reliability, and efficiency of their equipment.

Crane Capacity Verification

The first application note outlines a project in which the customer wanted to verify that their crane was strong enough to safely lift a heavy load at its rated maximum load capacity. It was determined that because of the size of the crane, a wireless solution was needed to avoid long wires and burdensome installation. Interface provided a WTSTL Lightweight Wireless Tension Link Load Cell to measure the load’s maximum capacity. WTS-RM1 Wireless Relay Output Receiver Modules were also used to trigger an alarm that can be set when the maximum capacity of weight/force has been reached. To review the data the customer could transmit the data to a PC or laptop with a WTS-BS-4 USB base station. The data can also be reviewed through a WTS-BS-1-HS Wireless Handheld Display. With this solution, the customer was able to verify if the crane is safe and functional enough to lift it’s working load limit (WLL), or safe working load (SWL) capacity.

Crane Block Safety Check

The next example features a crane application in which the customer wanted to detect whether a crane block could lift a heavy load securely to keep working conditions safe for personnel. The customer specifically wanted the solution to include an alarm feature that notified them if lifting capacity was exceeded in real-time. Using a WTSLP Wireless Stainless Steel Load Pin in place of a load bearing pin in the crane block, they could measure the force being applied by the heavy load. Data will be transmitted and displayed through both the WTS-BS-4 USB Base Station. It can also be paired with the WTS-BS-1-HA Wireless Handheld for real-time safety monitoring. The WTS-RM1 Wireless Relay Output Receiver Module triggers an alarm when maximum capacity has been reached. The customer was able to verify if the crane was operating safely and was always functional enough to lift it’s working load limit (WLL) or safe working load (SWL) capacity. The added alarm feature is critical for notifying users when the crane reaches unsafe limits during operations.

Crane Force Regulation 

In the final application note, a customer wanted to regulate the maximum number of heavy loads being lifted, so that production time was both safe for workers and efficient. The goal was to complete lifting duties faster and with little or no expense. A wireless solution was also preferred, so that there would be no long cable interference during production. Interface supplied a WTSLP Wireless Stainless Steel Load Pin, which can be custom made to be used for any and all types of cranes. It is also great for lifting both short and long distances. The load pin was paired with the WTS Wireless Telemetry System, where force could be measured and logged. The customer was able to monitor the continuous force from the crane, and gather information on loads being lifted for continuous safety and production reporting requirements.
