10.18.2 Imaging Sensor Temperature Conditions
The temperature sensor is used to monitor the temperature of the camera’s imaging sensor board.
The camera also has imaging sensor over temperature protection. An over temperature condition
is detected, if the temperature of the imaging sensor board rises above 75° C. Two stages can be
distinguished:
If the temperature of the imaging sensor board
rises above 90 % of the over temperature of 75° C (i.e. 67.5° C), a critical temperature
condition is detected. The camera function is unchanged as long as the temperature of the
imaging sensor does not rise above 75° C. If the temperature rises above 75° C, an over
temperature condition is detected (see next bullet point).
As soon as the temperature of the imaging sensor board falls below 80 % of the over
temperature (i.e. 63° C) the "critical temperature" status is reset.
For information on how to check for a critical temperature condition, see below.
rises above 75° C, an over temperature condition will be detected and the circuitry on the
imaging sensor board will switch off. In this situation, you will still be able to communicate with
the camera, however, the camera will not be able to acquire or transmit images. The imaging
sensor board circuitry will remain off until its temperature falls below 75° C. Once the
temperature is below 75°, the error condition will clear. After the error condition clears, the
camera must be restarted before it will begin operating normally.
For information on how to check for an over temperature condition, see below.
Checking for an Imaging Sensor Board Temperature Condition Using Basler
pylon
You can use the pylon API from within your application software to check whether the imaging
sensor board is currently in a critical temperature condition or in an overtemp condition. Checking
for the temperature condition using Basler pylon is a two step process:
Select the imaging sensor board temperature sensor.
Check for a critical temperature condition or an overtemp condition.
The following code snippet illustrates using the pylon API to read the temperature in degrees C:
// Select the imaging sensor board temperature sensor
Camera.TemperatureSelector.SetValue ( TemperatureSelector_Sensorboard
);
Depending on what temperature condition you want to check:
// Check for an imaging sensor board critical condition
bool imgSensorCriticalTemp = Camera.CriticalTemperature.GetValue();
// Check for an imaging sensor board overtemp condition
bool imgSensorOvertemp = Camera.OverTemperature.GetValue();
You can also use the Basler pylon Viewer application to easily check for an overtemperature
condition.
For more information about the pylon API and the pylon Viewer, see Section 3 on page 21.
