MPM Pressure Indicator/Transmitter with Alarms
DESCRIPTION The MPM family of panel meters incorporates the use of a microprocessor and a solid-state, silicone piezoresistive sensor. The microprocessor allows for no trim pots, all digital calibration and overall product flexibility. The MPM family of panel meters combines an indicator, a switch, and a transmitter, with a large, vibrant 3 1/2 digit LCD display, all in a compact, 1/8 DIN enclosure. On the MPM2, set point settings are easily made by the on-board, push-button adjustments. The MPM family of pressure panel meters features a “zero” adjustment, making mounting orientation flexible and easy — and (on the MPM2) the two on-board LEDs allow for bright visual indication of when a Hi and/or Lo point has been achieved. The MPM family of pressure panel meters may be ordered with dual relays providing for output switching. Typical applications would include those where a Hi and/or a Lo alarm point are important. The MPM family is available with a 2 or 7 amp failsafe configured relay. Models with relays also feature an easy-to-use, programmable deadband, which can be set for up to 25% of the range of the unit, in .100% increments. Relative accuracy is 0.5% of full range. The unit is fully compatible with air and other inert gases. Ranges are available up to 20" WCD and 5 kPaD. An optional gasket is available in order to make the faceplate meet NEMA 4 requirements. KEY FEATURES 3 1/2 Digit LCD Display All models have a 31/2 digit LCD display. Also the use of a membrane style keypad makes wipe down very easy. Analog Outputs/Hi-Lo Relay Set Points On certain models, a 4-20 mA or 0-5 vdc Analog output are available. Also, on certain models a hi and lo relay set point may be set by utilizing the “Mode” keypad button, as well as the “up arrow” keypad button. It allows you to easily scroll through the 31/2 digit display to arrive at a desired pressure set point.
