MZ-1A Oem High Range Pressure Switches
Product Information
The MZ_ _A / MX_ _A OEM High Range Pressure Switches are
pressure switches designed for industrial applications. They come
with a range selection table to choose the appropriate model code
based on the desired pressure range. These pressure switches have a
maximum working pressure ranging from 200 psi to 500 psi, depending
on the model. They are equipped with a SPDT snapaction microswitch
with an electrical rating of 15 Amp, 250 VAC. The enclosure is IP66
standard, featuring a transparent tough polycarbonate cover for
protection. The wetted parts are made of SS316 and Teflon, ensuring
durability and resistance to corrosive materials. The pressure port
is 1/4 NPTF standard and the cable gland is M20 x 1.5 standard
(polyamide). The maximum temperature of the working medium is 80°C,
and for higher temperatures, impulse tubing should be used.
Product Usage Instructions
- Select the appropriate model code from the Range Selection
table based on the desired pressure range. - Install the pressure switch according to the provided
installation drawing. - Ensure that the wetted parts mentioned in italics are properly
installed. - Connect the pressure port (SS316) to the desired system or
equipment. - Secure the pressure switch using the mounting bracket and four
cover locking screws. - Insert the cable through the cable entry and tighten the cable
gland (M20 x 1.5 standard). - Make sure the pressure switch is within the specified maximum
temperature limit (80°C). - For higher temperatures, use impulse tubing.
- Refer to the user manual for any additional information or
graphs related to minimum differential increases with
setpoint.
