In chemical tanks this means resistance to deterioration from chemical exposure. These rugged, compact ultrasonic level sensors measure a wide variety of liquids from diesel fuel in rail locomotives to chemical tanks in the paper and food processing industries (not suited for high temperature CIP operations). Heavy duty electronics are epoxy potted into a polyvinylidene fluoride (PVDF) housing that physically isolates the transducer and electronics from the chemicals and can withstand exposure to both acids and bases. They are used both indoors and out, and in some of the harshest factory environments. They are also used in liquid level applications where chemical resistance is not required.

All CHEM sensors include serial Data Communications to connect with SenixVIEW software or other equipment.
Models come with either an RS-232 or RS-485 interface, with the following communications format:
We recommend the RS-485 Serial Data Interface unless connecting to an RS-232 device. The benefits of RS-485 over RS-232 include:
If you only need a Serial Data interface all models are available without the analog and switch outputs at reduced cost and power consumption, and use a 4-wire dual twisted pair (plus drain) data cable instead of the standard 9-wire cable.
Multiple Simultaneous Outputs allow these sensors to connect with almost any type of equipment.
Ultimate Flexibility
All sensor outputs are SenixVIEW configurable by the user.
Any connection you need…
Send liquid levels wirelessly and view them on a LAN or in the cloud using our new AirWire LoRa transmitter:

SenixVIEW is included at no charge, runs on a Windows PC and connects to sensors via a serial data port. Our Setup Kits provide everything needed to connect through a USB port, including power supply, sensor-PC interface and cables. SenixVIEW is not required but adds powerful configuration, test and management capability.
