Description

HYDROCONT HP4

LEVEL SENSOR

The Hydrocont HP4 device is an electronic sensor for continuous monitoring, control and measurement of filling level and temperature. The high precision and digital setting of RS485 Modbus®-RTU make the Hydrocont HP4 suitable for a wide range of applications. Application form. The solid design and high performance make the device very good and unaffected by the worst conditions, such as the lowest temperatures, shock, vibration, or heavy discharge when used outdoors.

Tethered laser type marking ensures identity throughout the life of the device. Obviously, an option displays the name of the indicator resp. Label or customer support, TAG and laser marking. Linked to the LAB Silicone-free version, factory calibration with calibration certificate and customer-specific configuration resp. Optional presets are also available, such as EN10204 3.1 test data certificate or factory certification for drinking water connection. Customer-specific versions can be realized at short notice on request. special design or other process information.
