Fuel Level Probe Type CS-27/RS/U

Product catalog summary

Overview
The CS-27 Fuel Level Probe is designed for measuring fuel levels in motor vehicles, working machines, and locomotives. It is officially approved by the Ministry of Transport with Certificate No. E20 10R-03 25 17.

Function
The probe measures fuel levels using the hydrostatic pressure principle, which correlates the height of the liquid column to the pressure produced. It consists of a sensing element and an electronic element housed in a steel rod and aluminum casing.

Structure and Operation
The probe uses a piezoresistive sensor separated from the medium by a membrane. It measures pressure at the membrane, located 5 mm above the tank bottom. The pressure measurement is adjusted based on whether the tank is pressurized or not.

Assembly and Usage
The probe is mounted on the tank cover and can be connected to analog input data recorders or devices with a serial RS-232C port. Detailed assembly instructions are provided in the technical documentation.

Fuel Level Probe Type CS-27/RS/U Measuring range 0÷800 mm H2O Ministry of Transport Type Approval Certificate No. E20 10R-03 25 17 Function The CS-27 Fuel level probe is used to measure fuel level in the tanks of motor vehicles, working-machines and locomotives. The probes have been officially approved by the Ministry of Transport. Structure and Operation The measurement of fuel level with the CS-27 probe is performed with the use of a simple relation between the height of liquid column and the produced hydrostatic pressure. The probe is composed of two parts: the sensing element and the electronic element, placed inside a steel rod, and aluminum housing. The steel rod is fixed to an aluminum housing which may be sealed. The measuring element is a piezoresistive sensor, separated from the medium by a separating membrane. Pressure measuring is performed at the membrane of the submerged probe (5 mm above tank bottom). Depending on the type of tank (pressurized or nonpressurized tank), pressure measuring is related either to atmospheric pressure or pressure inside the tank. Assembly and Usage The CS-27 probe is mounted to the tank cover. A detailed description of assembly is presented in Technical Documentation. The probe is designed to be connected to the following recording devices: - analog input data recorder – current or voltage (current or voltage analog output probe). - recorder or PC computer equipped with a serial RS-232C port (digital output probe).
