1. External Sensors for Large Bore Valve TMS sensors measure pressure and temperature and estimate their own battery condition. Every sensor has a unique identity code (ID). The four-digit ID code is printed on the product. Periodically and on certain conditions, each sensor broadcasts its ID and measurements as a radio transmission. The TMS Canister can be screwed directly onto a large bore valve without the need to remove the valve stem. The key features are: TMS24, our standard sensor:  433.

1.3. Measurements We calibrate each sensor’s pressure measurement during manufacture. Sensors need to measure temperature in order to make an accurate pressure reading. The measurement may be of use depending on where sensors are mounted, bearing in mind that it is the temperature at the sensor PCB, not necessarily the air or tire.

1.6. Transmit on change In addition to the periodic transmissions, sensors also transmit if there has been a ‘change of pressure’: an increase or a decrease, since the previous transmission. When a sensor detects a change, it transmits the new pressure once immediately and then makes a number of ‘extra transmissions’ at subsequent sample intervals. Parameter description Sensor Change of pressure All Reaction time: this is time between change of pressure and first transmission.
