Meriam Instrument introduces MFT 4000, a new generation of multifunctional “smart” calibration equipment featuring HART digital communication protocol

Meriam Instrument introduces the microprocessor-based MFT 4000 — a hand held multifunctional tester that allows users to measure pressure, differential pressure and temperature; to measure voltage or current; and to calibrate field devices. Most significantly, the MFT 4000 is the only multifunctional, modular unit on the market with full HART digital communications capability. This provides the user with the ability to poll, configure and maintain HART compatible field devices with just one unit from the palm of their hand.

This new multifunctional tester/calibrator/communicator will benefit virtually any manufacturing or processing industry. Using the MFT 4000’s NIST traceable measurements and HART mode to check a field device provides the technician with one display for applied process value, measured value, analog output and the trim menu needed to return the field device to optimum performance. The technician will need just one tool, not two or three, to quickly and easily perform his task.

Meriam’s MFT 4000 consists of a portable (9.5” x 4”) base unit that encloses three bays for sensor modules. Two of the bays will accommodate a variety of available pressure modules. The third is an accessory bay for which customers can choose from a number of other measurement modules such as temperature or frequency. Advanced modules for other measurements and applications will also be available.

MFT 4000’s pressure modules are NIST traceable to ± 0.025% of full scale and are fully temperature compensated for best accuracy across a broad temperature range. Measurement of both current (mA) and DC voltage (volts) are integral to the base unit with ± 0.025% of full scale accuracy. The user can easily zero any installed sensor module or display minimum/maximum measurements. Displayed measurements can be dampened to remove jitter. A security code allows lockout of changes to all calibrator settings or can be limited to specific features. Other standard features include sensor module re-certification capability, self-testing and diagnostics and user-selectable automatic turnoff. MFT 4000 will offer options for popular calibration documentation packages, loop power and current/voltage sourcing, USB connection and hazardous environment testing.

The unit’s customized, red, ergonomically designed case introduces a new look for Meriam instrumentation and provides a new level of comfort for the user. MFT 4000 features an easy-to-read 128 x 128 pixel graphic display. Power is supplied by 6 AA batteries or an optional auxiliary power adapter.
