MFT 4000 has full Hart digital communications capability. It can be used to simulate or measure temperature; to measure pressure or differential pressure; to simulate or measure voltage or current; to calibrate field devices; and to document the performance of field devices. It consists of a portable base unit with three bays for sensor modules. RTD and thermocouple modules measure or simulate a range of temperature elements with NIST-traceable accuracy. The VMA module will temporarily power a 24 VDC loop, simulate or source current, or simulate VDC. Measurement of both current (mA) and DC voltage are integral to the base unit with ±0.025 percent of full-scale accuracy.
