Loctite 97211 In-line Flow Monitor Pre-amplifier

The Loctite In-line Flow Monitor Pre-amplifier (P/N: 97211, material number: 215992) provides effective monitoring of dispense cycle performance when integrated with the Loctite 97152 Dual Channel Automatic Controller, Dispense Valves; and Pressure Sensor Transducer 8965008.

The Loctite In-Line Flow Monitor amplifies a pressure signal from a dispense valve and relays it to the Controller to be compared against preset dispensing tolerances. The Controller will send an error alarm when dispense events deviate by more than the pre-set tolerance. The system will not allow another dispense cycle to occur until the error is cleared by an operator or external control source. The system can be used as an independent operator controlled work station or interface to an external PLC.
