Frequently Asked Questions
Q: What does the QPM11 adjustable air pressure switch controller do?
A: The QPM11 is an automatic pressure switch that monitors and controls air or hydraulic pressure within a system. When pressure reaches your pre-set threshold, the switch opens or closes the circuit (NO or NC mode), automatically starting or stopping a pump, compressor, or other connected equipment — keeping pressure within your desired range without manual intervention.
Q: What pressure range does the QPM11 controller support?
A: The QPM11 supports an adjustable pressure range of 0.1 to 1.0 MPa with a deviation of less than 3%, providing precise and reliable pressure regulation for most pneumatic and hydraulic applications.
Q: What thread sizes are compatible with this pressure switch?
A: This controller features both G1/8 and G1/4 threaded port options, making it compatible with a wide variety of compressors, pumps, and pneumatic systems.
Q: How durable is the QPM11 pressure switch?
A: The QPM11 is built from corrosion-resistant, high-grade materials designed to withstand abrasion and high-pressure impacts. It is rated for up to 1 million operating cycles, making it a long-lasting choice even in demanding industrial environments.
