# Configuration

Navigation: Valve Firmware > Pressure Sensor > # Configuration |

It’s important to do proper sensor configuration. The valve internally calculates in absolute values, so the valve needs to know what sensors are connected.

The CPA window Pressure Sensor shows a good overview of the available sensor settings.

Parameter | Description
Available | Set to True if a sensor is connected
Enable | Set to True if the sensor signal is used for pressure control
Input Source | Analog Digital Simulation | Sensor has an analog voltage interface and is direct connected to the valve. Sensor and Valve have EtherCAT interface and is connected to the EtherCAT bus Testing the valve and pressure control without being connected to the system
Range.Scale | Select type of the sensor signal Linear Logarithmic Most gauges are linear type gauges.
Range.Data Unit | Set the pressure data unit of the gauge: Pa, kPa, bar, mbar, Torr, mTorr, psia, psig
Range.Upper Limit Data Value Range.Lower Limit Data Value | Set the upper limit and lower limit of the gauge in the unit of Range.Data Unit Example for a 250mTorr linear sensor: Upper Limit = 250.0 Lower Limit = 0.0
Range.Upper Limit Voltage Value Range.Lower Limit Voltage Value | These parameters are only used for gauges with analog voltage interface. The values corresponds to Range.Upper Limit Data Value and Range Lower Limit Data Value Example: Upper Limit: 10.0V à 250mTorr Range Upper Limit Data Value Lower Limit: 0.0V à 0.0mTorr Range Lower Limit Data Value
Filter.Enable | True enables the filter
Filter.Type | Available since April 2021. Low-pass Simple is backwards compatible.
Filter.Time | Set filter time in the range of 0.0 to 1.0 second. Note: Filter delays the sensor signals which is detrimental for pressure control
