It is designed to be fully cleanable, supporting Protection Class IP69k to withstand high-pressure washdowns and steam cleaning.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,1,0\">CIP and SIP Readiness: The sensor is built to endure the extreme temperature cycles of Clean-in-Place (CIP) and Sterilization-in-Place (SIP) processes (up to 150\u00b0C), ensuring long-term reliability without compromising food safety.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,2,0\">IO-Link Connectivity: Integrated IO-Link allows for digital parameter setting and advanced diagnostics. This simplifies the configuration for machine builders and provides transparency into the sensor&#8217;s health and switching status.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,3,0\">Media Independence: Like all Liquiphant devices, the FTL33 uses vibronic technology. The switching point remains highly accurate regardless of changes in the liquid&#8217;s conductivity, density, or the presence of air bubbles and turbulence.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,4,0\">Self-Monitoring Safety: The device continuously monitors its own frequency and electronics. In the event of a power failure or internal fault, it defaults to a safe switching state, providing a reliable layer of overfill and leakage protection (WHG).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"3,5,0\">Plug &amp; Play Simplicity: No media adjustment or calibration is required. The sensor works &#8220;out of the box&#8221; for almost any pumpable liquid, requiring no specialized tools or software for basic operation.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"4\">\u0e15\u0e32\u0e23\u0e32\u0e07\u0e02\u0e49\u0e2d\u0e21\u0e39\u0e25\u0e08\u0e33\u0e40\u0e1e\u0e32\u0e30\u0e17\u0e32\u0e07\u0e40\u0e17\u0e04\u0e19\u0e34\u0e04<\/h3>\n<table data-path-to-node=\"5\">\n<thead>\n<tr>\n<td><strong>\u0e04\u0e38\u0e13\u0e2a\u0e21\u0e1a\u0e31\u0e15\u0e34<\/strong><\/td>\n<td><strong>\u0e23\u0e32\u0e22\u0e25\u0e30\u0e40\u0e2d\u0e35\u0e22\u0e14\u0e17\u0e32\u0e07\u0e40\u0e17\u0e04\u0e19\u0e34\u0e04<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span data-path-to-node=\"5,1,0,0\">\u0e2b\u0e25\u0e31\u0e01\u0e01\u0e32\u0e23\u0e27\u0e31\u0e14<\/span><\/td>\n<td><span data-path-to-node=\"5,1,1,0\">\u0e44\u0e27\u0e42\u0e1a\u0e23\u0e19\u0e34\u0e01 (\u0e2a\u0e49\u0e2d\u0e21\u0e40\u0e2a\u0e35\u0e22\u0e07)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,2,0,0\">\u0e01\u0e32\u0e23\u0e2d\u0e2d\u0e01\u0e41\u0e1a\u0e1a\u0e2d\u0e38\u0e1b\u0e01\u0e23\u0e13\u0e4c<\/span><\/td>\n<td><span data-path-to-node=\"5,2,1,0\">Compact hygienic stainless steel<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,3,0,0\">\u0e2d\u0e38\u0e13\u0e2b\u0e20\u0e39\u0e21\u0e34\u0e01\u0e23\u0e30\u0e1a\u0e27\u0e19\u0e01\u0e32\u0e23<\/span><\/td>\n<td><span data-path-to-node=\"5,3,1,0\">-40 \u0e16\u0e36\u0e07 +150 \u0e2d\u0e07\u0e28\u0e32\u0e40\u0e0b\u0e25\u0e40\u0e0b\u0e35\u0e22\u0e2a (-40 \u0e16\u0e36\u0e07 +302 \u0e2d\u0e07\u0e28\u0e32\u0e1f\u0e32\u0e40\u0e23\u0e19\u0e44\u0e2e\u0e15\u0e4c)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,4,0,0\">\u0e41\u0e23\u0e07\u0e14\u0e31\u0e19\u0e01\u0e23\u0e30\u0e1a\u0e27\u0e19\u0e01\u0e32\u0e23<\/span><\/td>\n<td><span data-path-to-node=\"5,4,1,0\">-1 \u0e16\u0e36\u0e07 +40 \u0e1a\u0e32\u0e23\u0e4c (-14.5 \u0e16\u0e36\u0e07 +580 psi)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,5,0,0\">\u0e04\u0e27\u0e32\u0e21\u0e2b\u0e22\u0e32\u0e1a\u0e02\u0e2d\u0e07\u0e1e\u0e37\u0e49\u0e19\u0e1c\u0e34\u0e27<\/span><\/td>\n<td><span data-path-to-node=\"5,5,1,0\">0.76 \u00b5m or 1.5 \u00b5m<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,6,0,0\">\u0e2a\u0e31\u0e0d\u0e0d\u0e32\u0e13\u0e40\u0e2d\u0e32\u0e15\u0e4c\u0e1e\u0e38\u0e15<\/span><\/td>\n<td><span data-path-to-node=\"5,6,1,0\">DC-PNP, IO-Link<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,7,0,0\">\u0e23\u0e30\u0e14\u0e31\u0e1a\u0e01\u0e32\u0e23\u0e1b\u0e49\u0e2d\u0e07\u0e01\u0e31\u0e19<\/span><\/td>\n<td><span data-path-to-node=\"5,7,1,0\">IP65\/67 or IP69k<\/span><\/td>\n<\/tr>\n<tr>\n<td><span data-path-to-node=\"5,8,0,0\">\u0e43\u0e1a\u0e23\u0e31\u0e1a\u0e23\u0e2d\u0e07<\/span><\/td>\n<td><span data-path-to-node=\"5,8,1,0\">WHG, FDA, 3-A, EHEDG<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h4 data-path-to-node=\"6\">\u0e01\u0e32\u0e23\u0e43\u0e0a\u0e49\u0e07\u0e32\u0e19\u0e2b\u0e25\u0e31\u0e01<\/h4>\n<ul data-path-to-node=\"7\">\n<li>\n<p data-path-to-node=\"7,0,0\">Pump Dry-Run Protection: Essential for protecting expensive hygienic pumps in beverage lines and dairy processing.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,1,0\">Overfill Prevention: Accurate high-level detection in mixing vessels, fermentation tanks, and storage containers for liquid food products.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,2,0\">Level Monitoring in Skids: Its small size is ideal for compact modular units like carbonation systems or small-scale pasteurizers.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"7,3,0\">Media Separation: Detecting the interface or presence of different hygienic liquids during process transitions.<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>The Liquiphant FTL33 is a high-performance, point level switch specifically engineered for the food and beverage industry.
