Madison M8000 Plastic Full Size Miniature Liquid Level Float Switch with Polypropylene Stem, 30 VA SPST, 1/8" NPT Male, 100 psig Pressure

Model: M8000   |    Mpn: M8000   |    Ean: 0094700750341   |    PartNumber: M8000   |   Asin: B00909404Y

Miniature liquid level switch has a polypropylene stem and a polypropylene float. Polypropylene is typically suitable for use with acidic liquids such as those found in electroplating and metal cleaning. It is also a great option for lower temperature food operations (up to 105 degrees C) since Madison only incorporates polypropylene that is FDA approved for food contact. This material is a good choice for commercial appliances and equipment as well. This elimates the need for more than multiple penetrations into the tank since both level and temperature may now be measured through one device. For acidic conditions, such as found in electroplating and metal cleaning. Another choice for lower-temperature (to 105 degree C) food processing applications. Maximum temperature: 105 degree C, 221 degree F. Fittings: 1/8" NPT, nominal current rating(s): 30 VA SPST switch. Float SG: 0.80, Maximum pressure: 100 psig. Lead wires: 22 gauge MTW 24", CE, CSA, NSF International UL approvals.
