The water level pressure sensor and temperature sensor are enclosed in a slim, robust 22 mm x 192 mm (7\/8\" x 7.55\") 316L stainless steel housing. Double O-ring seals prevent leaks, and a Faraday cage design protects against power surges and lightning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003cbr\u003eEach probe features a removable nose cone for optional use of the 1\/4\" NPTM threaded connection. The durable water level pressure sensor provides 0.05% FS accuracy with automatic temperature-compensated readings. There are six pressure ranges to choose from (5-200 m), with options for absolute (non-vented) and gauged (vented) pressure sensor setups.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eData Availability\u003c\/strong\u003e\u003cbr\u003eThe Water Level Temperature Sensor works with digital and analog protocols – MODBUS, SDI-12, and 4-20mA (add-on Current Loop Adaptor). They are easy to integrate into existing SCADA or PLC systems. Communication cable assemblies are available in lengths up to 300 meters. The cables are easily and securely attached to the sensor using a threaded connection. Simple PC software utilities are used to set up the sensor for the different protocols, perform simple diagnostics, and update sensor firmware if required. A USB-A programming cable is available for connection to the PC.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Solinst","offers":[{"title":"301 Water Level Temperature Sensor - M5 Absolute Part# 116473","offer_id":48875106730136,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true},{"title":"301 Water Level Temperature Sensor - M10 Absolute Part# 116867","offer_id":48875106762904,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true},{"title":"301 Water Level Temperature Sensor - M20 Absolute Part# 116868","offer_id":48875106795672,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true},{"title":"301 Water Level Temperature Sensor - M30 Absolute Part# 116869","offer_id":48875106828440,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true},{"title":"301 Water Level Temperature Sensor - M100 Absolute Part# 116870","offer_id":48875106861208,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true},{"title":"301 Water Level Temperature Sensor - M200 Absolute Part# 116871","offer_id":48875106893976,"sku":null,"price":311.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0331\/2300\/8647\/files\/Screenshot2026-04-14090809.jpg?v=1776172216","url":"https:\/\/www.whiteoakenv.com\/products\/solinst-3500-9500-well-cap-assembly-2-for-the-aquavent-levelsender-part-112767-copy","provider":"White Oak Environmental \u0026 Safety, LLC","version":"1.0","type":"link"}
