This capacitive level gauge is a reliable continuous measuring device tailored for diesel tanks. Benefiting from capacitance detecting principle with no moving parts, it features high precision, strong diesel resistance and optional explosion-proof design. With flexible probe length and easy field calibration, it serves stationary oil depots and mobile machinery fuel tanks efficiently while requiring minimal daily maintenance.

Applicable Ranges of Cable Float Level Switch
1. Medium conditions
Medium type: clean water, wastewater, oil, weak corrosive chemical liquid; unsuitable for high-viscosity paste, easy-crystallization and fibrous entangled medium.

1. Preparation before adjustment
Stop feeding and discharging liquid, stabilize tank liquid level; open the switch inspection cover on the side-mounted linkage assembly, prepare screwdriver and ruler.

Side-mounted float level switch contact capacity (divided into three types: micro-mechanical, reed switch, and explosion-proof intrinsically safe, according to industrial standards).

Four types of test methods for dielectric strength (withstand voltage) of float level switches (applicable to reed type/transmitter type, according to GB/T14536.17, GB/T21418, IEC60730)

Temperature rise limits for float level controllers (GB/T14048, IEC60947 general standards, reed/electromagnetic coil listed separately, temperature rise unit K=℃ temperature difference)

Dual float level switch – Risk assessment of brittle fracture under 196℃ liquid nitrogen conditions

The salt spray test of the dual float level switch is based on GB/T10125-2021 and ISO9227 neutral salt spray test specifications, using a 5% sodium chloride solution and a 35℃ test environment. It is divided into four corrosion resistance levels according to the usage environment, corresponding to different test durations.
