New Product Development: The NPI Process

The New Product Introduction (NPI) process helps guide Honeywell product creation from initial concept through to the launch. The phases include:

Idea proposal
Identify customer needs
Concept definition
Planning and specification
Development
Validation
Delivery, support, improvement and obsolescence

Before the project progresses to the next phase, a review is held. Reviews act as a quality assurance measure by assessing relevant market, technical and business information.

One of the most important parts of the NPI process is the Voice of the Customer (VOC) research. VOC data helps capture customer insights and needs, and then translate them into the new product.

The NPI process provides a framework to guide project teams through the product development cycle by helping everyone see how all the pieces fit together. All new BW Technologies products are being created with the NPI process. Everyday, we are working together to provide the best gas detectors backed by exceptional customer service and support.

Feature Accessory

MicroDock II: Customize your own kit for total mobility

Both the Heavy Duty Case Kit and the Hard Case Kit are the ideal solution for portable and automated calibration, test and record storage. Confi gure your kit to suit your needs.

Hard case kits hold one base station, one docking module and a 34 L cylinder of calibration gas. Choose between the following confi gurations:

Kit with one demand fl ow regulator (DFR) and no gas
Kit with one DFR, a 34 L cylinder of LEL, O2, CO or H2S calibration gas
Kit with one DFR, a 34 L cylinder of H2S calibration gas

Heavy duty case kits hold one base station, one to three docking modules and one to three 58 L cylinders of calibration gas in a foam-lined, waterproof heavy duty case. The following confi gurations are available:

Kit with one DFR, no gas
Kit with one DFR, a 58 L cylinder of LEL, O2, CO and H2S calibration gas
Kit with one DFR, a 58 L cylinder of H2S calibration gas

For gases other than those listed, order a kit without gas and order the gas separately.

Use the MicroDock II

confi gurator table to create a custom heavy duty case kit or hard case kit. The confi gurator is available at www.gasmonitors.com or in the 2009 price list.

Ask the Expert

The following question was posed to our Applications and Training Specialist, William Ball:

Question: We are using GasAlertMicro 5 gas detectors at both our training academy and in the fi eld. During the training exercises we prepare Tedlar bags with various gas mixtures such as iosbutylene and methane, and would like to incorporate phosphine into the training exercise. However, I?m concerned about the exhaust of these gases after they are processed through the instrument. How much of any specifi c gas is consumed by the sensors before it is exhausted by the instrument? Specifi cally, if we used a 5 ppm concentration of phosphine in Tedlar bags, would an unsafe amount be exhausted through the instrument?

Answer: The GasAlertMicro 5 Series personal safety gas detectors use an electrochemical sensor for the detection of toxic gases such as phosphine. The target gas is not consumed by this detection technology. The target gas is fuel for the electrochemical reaction that occurs within the sensor; the sensor is merely a catalyst for a specifi creaction and virtually nothing is consumed in most electrochemical sensors. You should assume the concentration of gas exhausted by the detector is the same concentration as that being introduced.

You also need to be aware the gases are quickly dissipated in the atmosphere. I do not know the volume of gas in your Tedlar bag. But I can give you some calculations based on using our 34 L non-refi llable cylinder of 5 ppm PH3 in a fresh air environment:

The volume of the 34 L non-refi llable cylinder is 1.2 cubic feet
Assume a room of 10? X 10? X 10? = 1,000 cubic feet
1.2 cubic feet = 0.12% of the volume of the room
5 ppm X .0012 = 0.006 ppm PH3 dissipated into a 1,000 cubic foot room

As indicated on all of our calibration gas cylinders, they are recommended for use in areas with adequate ventilation. I would suggest conducting the training demonstration under a fume hood.

Firmware version 5.0 has been released and is available for download on the BW Technologies by Honeywell website. Enhancements include:

Adjustments to the sensitivity of the LEL sensor now allow calibrations like pentane and propane.
The low battery alarm routine now includes audible notifi cation when in normal operation and in confi dence beep mode.
IR communication with the IR connectivity kit and the MicroDock II has been improved.

Upgrade your GasAlertMax XT with Fleet Manager 2.1 (or higher). Your GasAlertMax XT gas detector displays its current firmware revision on the LCD during start up.

Sensor Poisons and Contaminants

A personal safety gas detector cannot properly protect a worker if gas molecules cannot get into the sensor or if the sensors ability to detect the target gas has been compromised. High concentrations of sensor poisons can permanently damage sensors while chronic exposure can result in a gradual loss of sensitivity.

You can help prevent potential sensor damage by recognizing sensor poisons. Several cleaners, solvents and lubricants can contaminate and cause permanent damage to sensors. Before using cleaners, solvents and lubricants in close proximity to the detector sensors, review the following information.
