What's a Reference Target Accessory?
Senix, manufacturer of ToughSonic® ultrasonic level and distance sensors, now offers a unique Reference Target Temperature Compensation accessory.
What Does The Tool Do?
It uses an external reference target, located in the measurement path at the front of the sensor, to reduce fluctuations caused by diurnal shifts—or the difference between the highest and lowest temperatures in one day. For each measurement, the sensor makes two readings: one to locate the reference target, and one to the distant object. Any change in the speed of sound affects both measurements.
The reference target location is locked during calibration. Any change in its apparent position is applied proportionally to correct the distant object’s apparent location. The result? A more accurate measurement that's significantly less affected by ambient air temperature, diurnal temperature swings, sensor self-heating, sunshine warming the sensor, cold ambient temperatures, or vibration.
Field calibrations can be done at any time or temperature. SenixVIEW software makes configuration and adjustments even easier.
Get The Specifics
Here's some more details on the Reference Target Temperature Compensation accessory.
- NOT reliant on internal temperature sensing or separate temperature input
- Improves level and distance measurements by compensating for diurnal air temperature swings
- Ensures sensor is not affected by heat (I.e: By sunshine or external heat source)
- Can be calibrated in the field at any temperature
- Easy setup and use
The accessory is mounted on a 2″ universal threaded Delrin adaptor. After installation, the reference target features can be enabled on SenixVIEW software, which is included with the purchase of every ToughSonic sensor.
Reference target compensation accessories are available for Senix sensors that use either a 1″ NPT or 30mm threaded housing, such as the Senix ToughSonic 3 or 14.
