Simple design structure, small size, low price, and sufficiently high precision,Minihelic®ⅡThe table is designed as a disc type differential pressure gauge. It is our compact watch that is easy to read and can withstand pressure up toSafety work within 30PSIG Minihelic ®ⅡThe table can be directly installed on the diameterInside a 2-5/8 inch hole. The standard pressure connection is a pointed nose connector suitable for 3/16 "I.D. hoses; You can also choose a 1/8 "MNPT male thread connection. Minihelic ®ⅡThe internal diaphragm of the differential pressure gauge, together with the pressure relief diaphragm, serves as overpressure protectionOvervoltage beyond this will not damage the instrument. Having a removable panel and back cover allows for low-cost maintenance and repair.

The differential pressure gauge housing is made of fiberglass nylon castingThe panel is made of polycarbonate and can be used in harsh environments and high-pressure situations. Minihelic ®ⅡThe table has± 5% accuracy and low cost are suitable for various OEMs and end users. OEM applications include indoor air purification, respiratory medical equipment, air samplers, airflow hoods, and electronic air cooling systems. As an air filter table, Minihelic ®ⅡApplied to large fixed engines, compressors, ventilation equipment, and air handling equipment.Minihelic®ⅡType differential pressure gauge can replaceMagnehelic ® Type differential pressure gauge is used in situations where precision, sensitivity requirements are not high, and the differential pressure range does not vary significantly.

Pressure connection

A: Standard Minihelic ®ⅡThe differential pressure gauge provides two hook bolt pressure interfacesIt is integrated with the back shell of the differential pressure gauge and can be easily and quickly connected to a 3/16 "I.D. rubber or plastic tube

B: When applied to high-pressure situations, it can provide a 1/8 "MNPT positive snail mosquito interface

noteThe oval shaped overpressure discharge hole behind the instrument panel is located on the right side of the interface This outlet is connected to a diaphragm seal and releases air and pressure when the pressure reaches 75 PSI

install

Dwyer provides Minihelic ®ⅡInstallation components for differential pressure gauge panel installationWhen installing, open 2-5/8 "(67 mm) diameter holes on the panel, and the panel thickness can accommodate installation components up to 1/2" (13 mm). If necessary, surface installation can also be performed by inserting two 4-40 screws into the panel and fixing them to the instrument screw holes. Surface installation requires two reserved holes for two pressure joints.
