Shand & Jurs (L&J Technologies & L&J Engineering) products

The MCG 2100 is able to communicate with any of the L&J engineering Level Gauges. The calibrator is equipped with the ability to display the level reading, temperature reading and the discrete input status being sent back from the transmitter. This enables the operator to check the conditions of the field wiring and proper operation of the control room. In the troubleshooting mode, different types of faults are displayed on the LCD.

L&J Engineering has once again revolutionized the Transmitter market with its latest edition of the MCG 2000 Transmitter, the MCG 2000 MAX. The MCG 2000 MAX uses L&J’s revolutionary new absolute magnetic encoding (patent pending) to provide the greatest accuracy ever offered in the history of transmitters with 1/32 of an inch standard and with 1/64 of an inch accuracy as an available option. The reliability of the new MCG 2000 MAX is also greatly increased over the previous generation of transmitters due to the huge reduction in the number of parts used.

L&J engineering`s MCG 3630 Touch Panel Tank Monitor provides field polling support for level, temperature, BS&W and density. It displays information as text or in graphical format in bar graphs for multiple tanks. The MCG 3630 provides a touchscreen selectable system allowing the user to set gauge address, enable tanks for polling and scale factors for graphs.

A Convenient, Powerful Remote Monitor ; The MCG 8100 communicates and provides power to any of the L&J 81xx series magnetostrictive level probes or interstitial leak detection probes through a convenient 4 wire data highway. Up to 10 individual probes and 12 external sensors can be connected in parallel to the same MCG 8100, with the appropriate amount of I.S. barriers Through this data highway, the MCG 8100 can be used for product level, water level and product temperature in the tanks. Hydrocarbon sensors are also constantly checked by the unit for liquids or vapors. The unit`s 20 digit keypad, 4 line LCD display, and self-prompting menus make the MCG 8100 easy to program and operate for even the most inexperienced users.

The Only True Self Testing Probe. The MCG 1090 Level Alarm Probe brings state of the art technology to overfill protection. The competitors systems typically only check the wiring and probe electronics. The MCG 1090 includes a solenoid to physically move the displacer as an actual level would. In keeping with the L&J tradition, the MCG 1090 has gone a step further than the competition in providing high reliability and low maintenance. The MCG 1090 offers the most reliable protection available against dangerous and costly overfills.

The MCG 300 Resistance Temperature Device (RTD) measures spot temperature by outputting a resistance change to a gauge or transmitter. This change in resistance, which is directly proportional to temperature, is detected by a precision input bridge circuit in the transmitter. In addition to two element leads, a third reference lead is provided. The reference lead is used to remove lead wire resistance from the measurement of the temperature elements.

Dual Microprocessors: At the heart of the MCG 1600SFI is a high integration core microprocessor which can be customized to specific applications. A separate DSP microprocessor provides high speed measurement and algorithm processing for high accuracy, obstruction avoidance, self-calibration, and echo cancellation. All programmed and processed information can be displayed on the gauge’s 32-character LCD as well as an optional ground level display.

Standard Configuration: The MCG 3210i Intelligent Field Interface Card Rack is a powerful, flexible interface that allows L&J engineering host systems to communicate with field devices communicating L&J Tankway communication protocol, regulates the device power, signal, and voltage levels. Moreover, since each field wiring branch can be isolated using the MCG 3210i, a complete cable failure in one branch will not affect the remaining branches.

Cost effective installation, Easy upgrade to existing equipment, Automated wireless gauging of local and remote tank fields, Spread Spectrum Technology.

Brushless Design Eliminates Moving Parts: With only three moving parts (drum assembly, gear assembly, and stepper motor) and only two PC boards (the CPU and the strain gauge amplifier), L&J has minimized parts to ensure reliability. Brushless design eliminates the inherent problem of friction and wear on the contacts. The MCG 1500SFI is the most compact and lightest servo available today.
