In-situ oxygen measurement with
autocalibration
Emerson announces the Rosemount Analytical SPS 4001B, IMPS 4000 and MPS 3000 self triggering autocalibration systems for in-situ oxygen analysers
Emerson Process Management announces the Rosemount Analytical SPS 4001B, IMPS 4000 and MPS 3000 self triggering autocalibration systems for in-situ oxygen (O2) analysers When used in combination with the unique features of the Rosemount Analytical Oxymitter and World Class 3000 analysers, these cost-effective sequencers ensure that O2 measurements are always accurate without having to manually initiate calibrations - safely keeping workers off the stack and operations running at optimal efficiency

Upgrading possible for old DCS systems.
New connection, control and display migration products from Emerson permit the easy and rapid conversion from older generation automation systems to the new PlantWeb digital plant architecture.
The SPS 4001B Autocalibration Sequencer is designed for single probe applications, whereas the IMPS 4000 and MPS 3000 Multiprobe Autocalibration Sequencers are designed for applications with up to four O2 probes.
The units can be easily added to existing oxygen installations and are equipped with HART digital communications, enabling the user to set up, calibrate and troubleshoot from any location where the analyser 4-20 mA signal is terminated and accessible.
The industry-leading diagnostics and advanced communication capabilities of Rosemount Analytical gas analysers are part of the broad Emerson range of intelligent, digital field devices that power PlantWeb digital plant architecture.

Measurement instrument platform ramps up.
The Rosemount 3051S is the first measurement platform to enable flexible best practices for pressure, level and flow from just one instrument: production in Europe is ramping up to meet orders.
Further cost savings, increased plant availability, and enhanced safety and environmental compliance are achieved when these analysers are integrated into PlantWeb architecture.
The autocalibration systems in the SPS 4001B take full advantage of the unique Oxymitter 4000 "Calibration Recommended" diagnostics.
Once an hour, the Oxymitter initiates an on-line impedance measurement of the sensing cell, which directly correlates to the cell accuracy.
When necessary, this feature triggers a fully automatic calibration via the SPS 4001B, ensuring the O2 measurement is always accurate and eliminating needless and costly "time in service" calibrations.
The SPS 4001B features an IP56 (NEMA 4X) enclosure with fully accessible subcomponents for convenient maintenance.
The IMPS 4000 (ideal for Oxymitters) and MPS 3000 (ideal for World Class products) are designed to provide automatic calibration in applications with up to four O2 probes - taking full advantage of "Calibration Recommended" diagnostics available on Rosemount Analytical in-situ O2 probes.
Both systems feature an IP56 (NEMA 4X) enclosure and can accept voltages from 85-264 V, 50/60 Hz.
The SPS 4001B, IMPS 4000 and MPS 3000 provide many benefits when used with applications using O2 probes, these include minimised installation/maintenance costs and remote calibration. Request a free brochure from Emerson Process Management ...
