With Peak or Valley Hold enabled, the temperature of the target is held while the measurement is interrupted. How does Peak and Valley Hold Processing work? Successful applications include chocolate and toffee manufacture, and automotive paint curing.
In these cases, without signal processing, it could be impossible for an alarm or control system to monitor the measured temperature reading, and the reading could be of little use to the operator.Ĭalex sensors with the Peak or Valley Hold function offer a solution for monitoring the temperature of such targets.
Peak or Valley Hold Processing can also be configured to allow the sensor to measure the surface temperature of a liquid in a vat with a stirrer For example, there may be gaps between the items being measured on a moving conveyor, or a rotating stirrer in a vat of liquid might periodically enter the measurement area.Ī sensor with Peak or Valley Hold Processing can be configured to measure the surface temperature of an object on a moving conveyor In some applications, the infrared temperature sensor does not continuously have a good view of the target. What does this feature do, and when should you use it? Many of our infrared temperature sensors have a feature called Peak or Valley Hold Processing.
