3201 Pressure & Temperature Sensor for Mining Truck Nitrogen Struts
August 23, 2021
Mining trucks and vehicles are exposed to some of the most extreme environments in the Off-Highway Vehicle industry, including high temperatures, high shock and vibration characteristics, and exposure to the elements. Additionally, as the vehicle moves around the work site, the heavy load in the dump body can shift, causing spikes in the hydraulic system that controls the bed, steering, suspension, and brakes.
As feedback to and from the systems on the vehicle is being improved, more data is required by the on-board controllers of the vehicle. One of those additions is not only the active pressure in a particular system, but also the need to monitor the temperature of the fluids inside the system.
An example is a mining truck manufacturer that utilizes nitrogen-charged cylinders for its brakes and accumulators. Not only do they want to monitor the pressure of the nitrogen in the cylinders, but they also want to monitor the temperature to ensure that the system is operating within the correct parameters.
Challenge
Finding a single reliable, heavy-duty pressure sensor with a temperature output that can survive the mining truck environment
Many pressure sensor manufacturers offer sensors that can withstand the harsh conditions of the mining truck industry. However, few have the optional configuration of obtaining both pressure and temperature readings from a single device. Typically, you would need an access port for a single pressure sensor, and then a second access hole would be required for the temperature sensor. This extra access port incurs additional labor costs due to the increased potential for leaks in an extra area.
Solution
Gems 3201 Series Pressure Sensors with Dual Output
The Gems 3201 series Dual Output Pressure Sensors feature a single device that can read both pressure and temperature in a single sensor solution. The pressure is measured via the thin-film strain gauge inside the sensor. The same strain gauge utilizes a temperature-measuring component that, since it is built directly onto the strain gauge, can measure the temperature of your media (fluid, oil, gas, etc.). This way, the manufacturer has one access port but two outputs.
