Specialists in Liquid Level Indication 1. INTRODUCTION The Jerguson Model MTII4200 is a 4-20 mA, loop-powered HART compatible level transmitter intended to be used in conjunction with the Jerguson Magnicator II magnetic liquid level gage. The part number designator for the MTII4200 can be found below.

ENVIRONMENTAL Humidity: 0 to 100% R.H., non-condensing Electronics Operating Temperature: -30 to 160°F (-34 to 71°C) ambient Vessel Pressure: Dependent on float pressure rating, FIELD INSTALLATION Mounting: 3/4 in. NPT fitting or flange mounting Wiring: 2-wire connection, shielded cable or twisted pair to screw terminals through a 3/4 in.
4. ELECTRICAL CONNECTIONS AND WIRING PROCEDURES Electrical Connections Connect the 24 VDC power supply to the electronics module using the screw terminal block on the electronics module. A typical wiring arrangement is shown in Figure 3. Figure 3 Wiring Diagram For explosion-proof installations, wiring shall be in accordance with the National Electric Code ANSI/NFPA 70, Article 501- Shielded cable, twisted pair of 24 AWG or heavier should be used.
6. MAINTENANCE Magnicator II liquid level gauges use magnetostrictive technology and only have one moving part—the float. This technology ensures no scheduled maintenance or re-calibration is required. 6.1 Removal of Electronic Puck The MTII4200 gauge is designed so that the user may remove the electronics module for any reason, including repair or upgrading of the module.

NOTE: Be sure you have the transmitter loop #1 connected to a load of 250 to 500 Ohms. A unit installed in a control loop is a good example of this loop load. You may also use a load resistor in the range of the above value. 5.
17.) Press the arrow UP key (far left) so the screen will now display “Set Span?”. 18.) Move the float to the span location. 19.) Press Enter. 20.) The screen will display “Span (corresponding number)”. 21.) Press Enter to reset the (corresponding number) to span and hold for approximately 1-3 seconds. 22.) The screen will display “ACCEPT?”.
