MPS 3000 MULTIPROBE CALIBRATION GAS SEQUENCER

DESCRIPTION

Read the “Safety instructions for the wiring and installation of this appara- tus” at the front of this Instruction Bulletin. Failure to follow the safety instructions could result in serious injury or death.

D-1 DESCRIPTION

The Rosemount Analytical MPS 3000 Multi- probe Calibration Gas Sequencer provides automatic calibration gas sequencing for up to four probes. The MPS routes calibration gas to the selected probe under control of the CRE, IFT, or digital electronics package. The elec- tronics package can be preprogrammed by the user for automatic periodic recalibration, or manually initiated calibration through the keypad on the front of the electronics package. The calibration parameters held in the electronics package can be selected to automatically up- date after each

calibration.

The MPS is housed in a NEMA 4X (IP56) non- hazardous enclosure, Figure D-1.

NOTE

A single multichannel MPS cannot be shared among a number of CRE electronics.

The MPS, Figure D-2, consists of: an air pres- sure regulator, a terminal board, a flowmeter assembly (one for each probe, up to four per MPS), HI GAS solenoid, LO GAS solenoid, a manifold, and a power supply. Each flowmeter assembly contains a probe solenoid.

An optional Z-purge arrangement is available for hazardous area classification. See Application Data Bulletin AD 106-300B.

D-2 THEORY OF OPERATION

A typical automatic calibration setup is shown in Figure D-3. The MPS 3000 Multiprobe Calibra- tion Gas Sequencer operates under the control of the CRE, IFT, or digital electronics package. When the electronics package initializes auto- matic calibration, the solenoid controlling the selected probe is energized. Next, the solenoid controlling calibration gas 1 (high O2) energizes allowing calibration gas 1 to flow to that probe. After the probe measures the oxygen concen- tration of calibration gas 1, the gas solenoid is deenergized. An operator selected time delay allows the gas to clear the system. Next, the solenoid controlling calibration gas 2 (low O2) energizes and allows calibration gas 2 to flow to the probe. After the probe measures the oxygen concentration of calibration gas 2, the gas and probe solenoids deenergize. The automatic calibration is now complete for the probe selected.
