MDM23-G51-03P

The MDM23-G51-03P is a high-performance, low-cost diaphragm-type pressure switch developed and manufactured by Lee Controls specifically for industrial applications. This device is a limited-range apparatus designed to detect and regulate changes in its pressure source. It can be used in a variety of industrial settings and is capable of setting its set-point while in operation.

It utilizes a thin durable diaphragm to detect small changes in pressure, and by use of a calibrated spring it adjusts the pre-set point activity. The switch consists of three basic parts – the diaphragm, the calibrated spring and the contacts. When the pressure reaches the preset point on the switch, the contacts open and close accordingly to indicate the detected pressure range.

The diaphragm is the most important part of the switch. It consists of a flat flexible membrane that responds to changes in pressure by expanding or contracting according to its stress. The calibrated spring adjusts the pre-set points of the device thus controlling the output. The contacts act as a final response to the existing pressure.

The MDM23-G51-03P is mostly used for controlling industrial machinery and equipment, particularly in the fields of centralized heat control and other temperature-related processes. It is an ideal choice for applications where a small change in pressure needs to be detected and regulated according to preset points. It can operate reliably in highly alkaline environments, is resistant to temperature-induced pressure variations, and is very dependable.

The MDM23-G51-03P has a knob for manual adjustment of the pre-set point (set-point) and has a pressure range of 0-10.5 bar (1.5 – 15 PSI) with a 1/8 NPT process connection. It has a temperature range of 0-80°C (32-176°F). It is CE marked for use in all European countries as per EN 61000-6-4 and CSA C22.2 No. 14-91 standards.

The MDM23-G51-03P is a reliable, cost effective and versatile pressure switch that is suitable for a variety of industrial applications. With its accurate sensing ability and rugged design, it offers dependable performance year after year.
