Control module ACM
The Ankersmid ACM Module has a Siemens Touch-screen PLC S7, panel filter type APF, moisture sensor ALA 002, calibration valves (zero/span) for calibration via cooler or probe, back-purge output, ultrasonic flow sensor and a gas pump integrated. Depending on the ACM version the gas pump can be flow-adjusted or static. A remote control for calibration and back-purge as well as MODBUS and USB-output and output alarm relays are implemented.

Additional information
The gas flow is measured and monitored by an integrated ultrasonic flow sensor. High/low flow alarm levels can be set customized.
The versions ACM 110 and ACM 120 are including a flow-controlled gas pump. In combination with the integrated ultrasonic flow sensor the system is able to compensate a flow loss which may occur due to clogging filters or variable process flow conditions.

The PLC S7 is able to monitor and control a heated gas sample probe and furthermore to operate various back-purge procedures.
The integrated optical moisture sensor can detect any kind of liquid, conductive and non-conductive. The gas pump will be switched-off automatically in case of liquid inrush.

For all connected devices detailed spare part lists can be shown directly on the PLC display.

Application
The ACM Control module for 19”-rack mounting is a modular system used as compact all-in-one device to monitor and control all gas sampling and gas conditioning equipment such as sample probe, cooler, sample line, pump and flow of gas media.
