2.1.10. Pressure Sensor
This is an MPX5100AP calibrated pressure sensor, which can measure the required air
pressure and vacuum. The Pressure Sensor is connected directly to the PPB card.
The pressure sensor can operate from +5V only. It is a calibrated sensor with 0-1.1 Bar input
range. Do not apply more than 1.5 Bar to it, because it can ruin the pressure sensor.
2.1.11. Digital Reagent Sensor Board
This board contains four liquid detector opto-detectors (optos) and a reference opto for
automatic temperature and stray light compensation. The reference opto is located in the
middle and it has the same temperature and backlight conditions as the sensing ones.
The Reagent Sensor Board is connected to the PPB card, and the valve driver micro-
controller makes the sensing and compensating operations.
Instrument makes automatic initialization called calibration of reagent sensors during
priming phase of fluidics.
