KX-SENTRY M1

Thermal Monitoring & Leak Detection Gateway

A DIN-rail gateway that watches 64 thermal points and up to 200 m of leak rope, and tells your DCIM before anyone smells trouble.

The first question every operations director asks about liquid cooling is what happens when it leaks. The M1 is our answer, and it is deliberately not a software answer.

Detection that does not need the network

Sensing rope runs under the CDU, along the manifold drip path and beneath the tank. When it wets anywhere along up to 200 m, the M1 locates the event to within a metre and closes a dry contact. That contact can trip the CDU directly. No server, no agent, no cloud service and no DNS lookup sits between the water and the shutdown.

Sixty-four points of the truth

Supply and return temperature at every branch, differential pressure across every filter, flow at every manifold. Sampled every second and held locally for thirty days, so when someone asks what the loop was doing at 03:14 last Tuesday there is an actual answer.

Speaking your building’s language

Modbus TCP for the mechanical contractor, BACnet/IP for the BMS, SNMP v3 for the DCIM. All three at once, from the same gateway, without a translation appliance.
