Water Depth (Level) Sensor

This is an amazing digital pressure sensor from Intersema has wide range applications.The MS5540C pressure sensor measures Absolute water or air pressure. It also measure temperature at the same time. So you can use it for measuring water depth in sea or water level in tank. It can be also be used with different fluids measurements such as oil. You might use it also with air for measuring altitude (barometer) and temperature. The MS5540C carries a metal protection cap filled with silicone gel for enhanced protection against water and humidity. The properties of this gel ensure function of the sensor even when in direct water contact. The MS5540C is qualified referring to the ISO Standard 2281 and can withstand a pressure of 100 m in salt water. Nevertheless the user should avoid drying of hard materials like for example salt particles on the silicone gel surface. In this case it is better to rinse with clean water afterwards. The sensor measure water depth with very good accuracy of 0.1 mbar (1 cm water level). Please read note 3 below for linear range and accuracy. The pressure module have wide range applications ranging from liquid level measurements in tanks, water depth and temperature in diving, snorkeling and ROV. The pressure sensor is factory calibrated and future electronics Egypt has extensively tested the sensor and prepared a tutorial (check below) showing how to read factory calibration coefficients and use it to measure both pressure and temperature in an accurate manner.
