Reliable Protection... the only probe on the market with full self testing
The MCG 1090 Level Alarm Probe brings high technology to over fill protection. The competitors system typically
check the wiring and probe electronics. The MCG 1090 also 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 over fills.
Remote Self-Checking
Typically, a Level Alarm Probe is mounted in a poor environment and sits inactive for years at a time. This makes
regularly scheduled testing the most important factor in reliability. The optional remote self-testing feature of the MCG
1090 makes regular testing of the probe easy and convenient. The probe can be wired to be tested from tankside or the
control room. If coupled with the L&J MCG 7000 Alarm System, all probes can be automatically tested at pre-programmed
intervals, complete with a printout of probe conditions.
Field Wiring
Two wiring configurations are available with the MCG 1090 Probe. Where independent wiring is required, individual wiring
from each probe may be run directly to the control room or alarm panel. If independent wiring is not required, a standard
4-wire data highway can be used to multiplex up to 128 probes to the MCG 7000 Alarm Controller.
Remote Data Acquisition
For a complete alarm system the MCG 1090 probe can be coupled to the MCG 7000 Alarm System. The MCG 7000
provides automatic self-checking, printouts, and discrete outputs for horns, emergency shut-off, etc., as well as an
optional communications port. The MCG 1090 can be configured with the standard L&J 4-Wire Data Highway port to
provide remote alarm data acquisition for your gauging and/or SCADA system (MCG 3900) along existing
wiring.
