360 Unità di controllo della Conducibilità
CONDUCTIVITY (TDS) PROBE
360 Conductivity Control Unit
It is an electronic device to be positioned on the door of an electrical panel or internally on a DIN rail.
Electrically connected to a 310/330 series probe, it is used to measure the conductivity (also called TDS) of the water in a boiler, giving a 4÷20mA current signal, and controlling 2 threshold relays.
Product Description
The 360 is an electronic device designed to be positioned inside the door of an electrical panel. Designed for connection to 310 series probes (positioned directly in the boiler) or 330 series probes (placed along the supply pipe), it accurately measures the conductivity (or TDS) of the water inside a boiler.
Main Features and Functions:
Conductivity Measurement: Capable of detecting values between 5 microS/cm and 10.000 microS/cm.
Output Signal: Delivers a normalized current (4÷20mA) proportional to the conductivity. This signal, galvanically isolated, can be sent to a PLC to control a valve, ensuring the entry of fresh and pure water when the conductivity is excessive.
Control Relay: It has two relays: one for managing the purge valve and the other to activate an alarm in the event of excessively high conductivity.
User Interface: Equipped with a front mini-terminal with 6 keys and an 8×2 character LCD display for calibration operations.
Connectivity: It has a USB serial interface, ideal for calibration, setting and reading operations.
Importance of TDS Measurement: Constant monitoring of dissolved salts (TDS – Total Dissolved Salt) in boiler water is essential, both to guarantee the purity of the steam (for example, for food or pharmaceutical applications) and to optimize methane consumption. Conductivity is directly related to TDS, making this device an essential “salinometer” for boilermakers.
