Tsurumi has developed a conical ram protection cover made of solid sheet steel to guarantee protection of the built-in water level sensor even in the event of a violent impact.
The installation is simple and once the protective cover is in place the sensor is protected from external damage. The sensor on Tsurumi pumps, such as the KTVE and KTZE series, is already protected to a degree. Its flexible rubber bend absorbs shocks quite effectively, although not entirely. The company says the new protection cover almost entirely rules out mechanical damage to the sensor.
Sensor pumps allow the device to control itself. If the water rises to a certain level, the unit starts up and switches off again when the level drops, saving operating costs. The ram protection safeguards this function.
Tsurumi relies on electrodes to measure the water level, which is safer as it does not rely on mechanics and electrodes react faster and are usually more accurate. As all measuring instruments are vulnerable, the recommendation to pump operators is to install low-cost ram protection.
