MCG 1500SFI Smart Flash Infrared Servo Gauge

Brushless Design Eliminates Moving Parts
With only 3 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.

Calibration Made Simple
The versatile MCG 1500SFI incorporates various self-calibration procedures to ensure absolute integrity as well as accuracy. Routines which are built into the processor have been designed to compensate for any possible product build-up on the displacer or any “give” or “play” in the cable.

Engineered For High Performance
± 0.4mm accuracy provides the highest accuracy available in servo technology. The servo housing is divided into two sections, the drum chamber and the electronics chamber. The drum chamber is isolated from the electronics chamber by a magnetic coupling. The electronic chamber is a gas tight, explosion proof housing which isolates the electrical components from both the product environment and the atmosphere. The MCG 1500SFI typically communicates using the standard L&J Tankway 4-wire data highway, yet simple plug-in modules can be utilized to provide for emulation of most existing, as well as custom field protocols or analog outputs.

Ground Level Display
The optional Ground Level Display (MCG 1350M) is a remote LCD display which is identical in form and function to the display on the main unit. It enables complete programming and calibration functions via the hand held I/R calibrator, MCG 2150.

Inventory Management
The MCG 1500SFI, which transmits level and temperature data, can be remotely accessed by a computer/receiver such as the MCG 3900 via the L&J Tankway. Product temperature is obtained by using a 3-wire R.T.D. (copper or platinum), or a MCG 350/351 averaging temperature probe with a MCG 2350 which is connected to an on-board analog-to-digital converter. It is no longer necessary to climb to the top of the tank to access the desired information or perform any of the programming functions. Simple plug-in highway interface modules emulate any existing, as well as custom field protocols or analog outputs. New or updated programs can be downloaded to any MCG 1500SFI into its on-board flash memory “on the fly” to incorporate communication protocol changes and additional functionality.
