Product Introduction
General Introduction
The RSA is a resistive water level sensor developed by TBB. As one of the core functional components of TBB’s system solutions, the RSA has been widely used in RVs, boats, special vehicles, and other fields. It consists of five stainless steel probes of different lengths, a plastic housing, and a wiring harness. The sensor has four levels: 25%, 50%, 75%, and 100%, enabling real-time detection of water tank levels.
Working Principle
The RSA is a resistive water level sensor. The longest stainless steel probe serves as the common electrode. By detecting whether the other stainless steel probes come into contact with the water level, changes in voltage are generated to determine the remaining water level in the tank.

Installation
- Drill a hole at the cover of the service open. The recommended cutout diameter is 37~38mm. The product dimensions are as follows.
- Pass RSA through that hole on service open from bottom to up.
- Pass screw cap of RSA through cable and fix it with thread body.
- Well fix the screw cap with thread body by proper tool to prevent any leakage or loose.
- Fix cover of service open back. The installation of RSA is finished.
Remarks
- Please keep the installation of RSA away from the water inlet with a distance at least 10cm. Or it will cause measurement is not accurate.
- The probe length has been calibrated by the manufacturer before delivery to the customer. It’s not allowed to cut probe length by user.
