 Beta Testers Wanted

 We are currently developing a process controller.  We are looking for beta test sites in northern California.  Equipment and services will be provided at no cost.  For more information, please contact us.

 Product Description

The Process Controller is reliable, accurate and suitable for measuring all types of  2  and  3  wire sensors with   4  - 20mA  outputs  including  all  of  Global Water’s  sensors.  The  controller  comes  pre-programmed  for use with 10 different sensors and 14 engineering units.  In addition, the PC300 can be programmed at the factory to monitor any type of custom sensor in any units selected by the customer.  The controller can also monitor sensors with voltage outputs if specified at the time of purchase.

 Display and Outputs

The LCD display shows the type of sensor that is being monitored, the data reading and the engineering units.  The display also indicates if either relay has been triggered since last reset, which relay was triggered and whether the maximum or minimum limit was exceeded.  Two separate relays are provided for controlling all types of external devices including samplers, alarms, mixers, pumps, control valves, floodgates and telemetry systems.  Each relay is independently programmable to trigger on maximum and/or minimum levels in one of three different modes.

Installation

The Process Controller has many applications and therefore many installation solutions.  The case is rugged and can be easily installed in a variety of conditions.  Four screw holes are provided for securing the case to a wall, panel or different types of mounting hardware.  While the case is watertight and will resist moisture, Global Water does not recommended that the PC300 be mounted outdoors without providing protection from continuous exposure to the weather.
