The MT220 can measure pressure with outstanding accuracy, high resolution, minimal tempco, and excellent stability. It offers a wealth of functions for field calibration, including transmitter output measurement (DCV/DCA functions), 24 Volts DC output, percentage error readout, measurement data memory, and Ni-Cd battery operation. The D/A conversion output makes it simple to output data to a recorder or other equipment. And of course, data output through a GP-IB or RS-232 interface is also possible-including data output during operation on a 12 Volt DC power supply or Ni-Cd batteries.
High accuracy: ±0.01%, with a maximum allowable input of 500kPa (130kPa range model).
Measurement with DC Volts and DC Amps.
24 Volt DC output.
Measurement data memory.
D/A conversion output, comparator output, and external trigger input (Optional).
GP-IB or RS-232 interfaces.
12 Volt DC power supply.
Battery operation (optional).
Std. Accessories: Connector for DC power supply, two rubber pads for rear foot, labels for indicating measurement object, one test lead, power cord and user’s manual.
Overall structural view of the Yokogawa original silicon resonant sensor*, a major factor in the high performance of the MT210/MT210F series.
Note*: Technology that has won the Ohkochi Grand Technology Prize and the Chairman’s Award of the Japan Federation of Economic Organizations (Keidanren).
