Kobold PMP-1050-N2-D042 Product Overview
The Kobold PMP-1050-N2-D042 is a high-precision microprocessor-controlled differential pressure sensor and transmitting switch designed specifically to measure, monitor, and regulate low air and non-corrosive gas pressures. Housed in a rugged IP65 polycarbonate enclosure, this advanced controller is primarily utilized for filter monitoring systems, cleanroom environments, and industrial ventilation networks to automate cleaning cycles and trigger system alarms.

Advanced Filter Management and Automated Rinsing Logic
The PMP-1050-N2-D042 serves as an intelligent asset for monitoring differential pressure before and after filter chambers or dust-collecting baghouses. As dust accumulation blocks gas flow, the building pressure drop rises. When a user-defined threshold is met, the primary integrated relay trips to initiate an automated pulsed-air filter-cleaning loop or backwash cycle via industrial solenoid valves. The secondary relay can be assigned as a critical high-limit system alarm, allowing facilities to optimize cartridge lifetimes while cutting compressed air consumption.
Microprocessor Calibration and Simplified Integration
Equipped with an intuitive local control face, the device features fully programmable parameters including relay hysteresis, trip delay timers, and analog span adjustments. The dual 1/4″ NPT process connections provide robust, leak-free plumbing into standard pneumatic instrumentation lines. With its continuous 4–20 mA loop transmission, this 230 VAC model integrates into centralized building automation systems (BAS), distributed control systems (DCS), or remote PLC monitoring stations.
