Float Switch

1, temperature: PVDF maximum temperature of 120 , PP up to 80 , PA maximum temperature of 105 SUS304/316 up to 200 . 2.pressure: plastic float voltage maximum 5kg/cm2, SUS float voltage maximum 30kg/cm 3, adhesion: the ball should be chosen large, the proportion of small float to overcome the liquid surface tension. 4, Resistance: PVDF plastic material applied to acid-base sites, H2SO4 sulfuric acid should be considered if the temperature selected PVDF. PP plastic material applied to HCl hydrochloric acid sites. NBR rubber applied to oil. 5, essential oils: should use the stainless steel material. 6, specific gravity: the proportion of SG float must be less than the measured liquid, or float is not floating up 7 explosion-proof protection level: according to customer asked to choose a variety of junction box, junction box, complete specifications, there are plastic, aluminum, stainless steel Explosion-proof, protection class IP-65 up to more than 8, the electrical switch form: Contact capacity 50W/250VAC SPST or 40W/250VAC SPDT 9, installation of connections: connecting flange with JIS, DIN, ANSI specifications; thread teeth I have NPT , PF, BSP, M, UNC and other specifications, and pay attention to the mounting holes the size of the problem with the float. 10, guide bar length: refers to the installation base level to the bottom of the length guide rod.
