# Crossover (2 sensor operation)

Navigation: Valve Firmware > Pressure Sensor > # Crossover (2 sensor operation) |

When two sensors are used (enabled) for pressure control the crossover handles the two pressure signals to building one system pressure (Actual Pressure).

Parameter | Description
Crossover Mode | Crossover between 2 sensors (see below)
Threshold High [SFS low sensor] Threshold Low [SFS low sensor] | Defines the crossover area (see below) The value is related to sensor full scale of low sensor (0.1 means 10% of sensor full scale of low sensor)
Delay | Switch over delay in Crossover Mode Hard Switch

Crossover Mode Soft Switch |
| Within the threshold levels, the resulting measurement value is a summation of the two sensors signals with a proportional ratio of the two measured values. When to use This is the standard mode. Values of both sensors need to fit together in the crossover area, otherwise crossover effect result (nonlinearity). Therefore, sensor ratio should not be too high (about <= 100).
Crossover Mode Hard Switch |
| Switching between sensors according to the hysteresis threshold levels and an optional delay. When to use Preferred setting if the sensor signals do not fit together in the crossover area (for example if sensor ratio is high).
Crossover Mode Target Pressure |
| If target pressure is in the range of low sensor, low sensor is used; otherwise high range sensor. When to use As there is no switchover during pressure control while using this setting, undesired effects like nonlinearity or continuous switching between sensors don’t occur. Note While in position control mode, ‘Soft Switch’ mode is used. In case of soft pump controller only high sensor is used. (newer firmware version Dec. 2020)
