What sizes are sensors available in?
Answer: We have sensors in many shapes and sizes. Please refer to our catalogs to see diagrams of our standard sensors. Contact Holykell for the sensor that would best fit your application. Custom sensors are also available.
What is the temperature range for sensor use?
Answer: Standard Holykell sensors are specified to operate in a temperature range from -40 ºC to 60 ºC. If the sensor is used at a temperature different than the calibration temperature, there will be a temperature effect.
We do also have High Temperature model sensors; they are specified to operate in a temperature range from -40 ºC to 200 ºC. Calibration would be affected when the temperature goes beyond this specified range.
What is the resistance range of a Holykell sensor?
Answer: The resistance range of the sensor is typically from > 5MΩ at no load to approximately 5kΩ at full load. This can vary depending on the electronics being used to drive and read the sensor.
What is calibration?
Answer: Calibration is the method by which the digital output of the system is converted to an actual engineering unit. Calibration enables you to compare the output of the same sensor in various environments and allows you to compare calibrated outputs of various sensors.
What is the lifetime of a Holykell sensor?
Answer: The durability of the Holykell sensor depends on the conditions to which it is exposed.
The sensor was tested under "normal" conditions with a 50 lb impact load on the sensor, which was between two pieces of metal. 1,000,000 cycles/hits were achieved. Upon completion of the tests, the sensor still provided an output proportional to applied load.
Can Holykell sensors be cut or trimmed?
Answer: Several of our sensors can be cut or trimmed to smaller sizes or shapes. For example, this is one of the most important advantages of our level sensor, which can be trimmed.
How do I clean Holykell sensors?
Answer: You can wipe our sensors clean with alcohol or water.
Can I customize a Holykell sensor?
Answer: Yes. If you cannot find a sensor that fits your application needs in our standard selection, we can work with you to custom design and manufacture a sensor. Your sales representative can provide you with additional information.
Are Holykell sensors waterproof?
Answer: Holykell HPT200 Series and HPT300-S series sensors are water resistant, but not water proof -- water will eventually seep in if left submersed. That is why we recommend resealing them with another adhesive if the sensor will be exposed to water.When water or other liquids are involved in the measurement, it may be desirable to achieve a perimeter seal around the sensor.
