Gems Sensors’ single-point level switches are designed to detect a specific liquid level—either high or low—and trigger alerts or system responses. These compact sensors are ideal for tank level monitoring, leak detection, and overflow protection across a wide range of industries. Choose from float-based, electro-optic, capacitive, and ultrasonic models to suit your fluid type, tank design, and environmental conditions.

The IRU-5000 is a short range ultrasonic sensor for small tanks and totes. It features an operating range of 4 inches up to 79 inches, making it ideal for smaller vessels where accurate level measurement is needed. With CSA, Class 1, Div 2 approvals, it is suitable for many hazardous locations. The IRU-500 series has three different mounting options 1-inch NPT, 2-inch NPT or a 2-inch sanitary ferrule.

The IRU-5000 ultrasonic sensor offers 4-20 mA and programmable voltage outputs. It also can be configured using NPN trip points, if you desire to trigger an alarm when liquids reach a certain level in the tank. With a blanking distance of only 4 inches, this sensor can be used reliably in small tanks containing expensive chemicals.

Features:
• Short range up to 79 inches
• Small blanking distance of just 4 inches
• CSA, Class 1, Div 2 hazardous location approvals
• 1-inch NPT, 2-inch NPT and 2-inch sanitary ferrule mounting options
• NPN trip points for setting level alarms

Applications:
• Liquid level measurement in small tanks up to 79 inches
• Environments requiring hazardous location approvals
• Sanitary applications where non-contact sensors are preferable

The LOE non-contact ultrasonic sensor is for measuring liquids in tanks up to 40 feet. This sensor is designed specifically for remote level measurement using an Internet connection to set up the sensor and view your level data. The LOE is very economical as the sensor design is simple and free of keypads and displays that add to the cost. Instead, all programming is done remotely from a PC, iPad or SmartPhone - anywhere you have a network connection. You simply access the BinView web site, enter your proprietary login credentials, and you have access to our robust, easy-to-use, tank monitoring system.

The LOE is available with either a 2-inch or 3-inch NPT for simple installation. With Class 1, Div 2 hazardous location approvals, it can be installed most anywhere. Communication with the LOE is easy - simply plug in an Ethernet cable to connect it to the Internet. From there, you have complete control to remotely set up and monitor one or many tanks at one or many locations without ever leaving the office. Our intuitive interface offers real-time level data, historical data logging, email and text alarms, and advanced reporting all packaged in an intuitive user interface.

The MNU ultrasonic sensor  is designed for liquid level monitoring in locations that do not require hazardous location approvals. The sensor is offered in a variety of ranges up to 40 feet. What makes it special is its compatibility with any Modbus controller or PLC with an RS-485 Modbus RTU ouput. This makes it a cinch to apply in any plant operation already using the Modbus protocol.

It's available with 1", 2" or 3" NPT mounting, making it adaptable to many types of tanks. Plus, it is extremely easy to set up using simple daisy-chain wiring or remote configuration via the Internet.The MNU can be used with the MND local display unit for on-the-spot monitoring. For anywhere, anytime inventory monitoring, the MNU is compatible with BinView remote monitoring for easy cloud access to your data.

Features:
• Measuring range up to 40 feet                                         
• Non-contact sensor designed for Modbus compatibility
• RS-485 Modbus communication
• BinView compatible for remote monitoring
• No hazardous location approvals

Applications:
• Tanks up to 40 feet tall containing liquids
• Non-hazardous environments
