Pressure Sensor Node (SD-PSN-2)
The Pressure Sensor Node is capable of reproducing the function of a traditional wired pressure sensor in a much more convenient package which can be deployed and managed much more easily than wired sensors.
The KCF Pressure Sensor Node Consists of two distinct parts:
Pressure Transducer: this is a traditional industrial pressure transducer that would typically be hard-wired to a data collection box. Pressure transducers output either a voltage or a current proportional to the pressure their sensing element is exposed to. The pressure transducer must be plumbed into the fluid system, and exposed to the working fluid, e.g. via a "T" fitting in a pipe.
Wireless Pressure Sensor Node: KCF's pressure Sensor Node connects to the pressure transducer via a short cable and uses a wireless link to replace the traditional wired path back to the data collection unit, eliminating the need to run cables to every point where pressure is monitored. The wireless Node does not need to be exposed to the process fluid being measured. It can be mounted magnetically or with a threaded stud anywhere in the vicinity of the pressure transducer as allowed by the short transducer cable
SmartDiagnostics® can predict failure before it occurs, saving money spent on unnecessary replacements and extending machine life. At the same time, energy costs are reduced, as cleaner running machines are more efficient.

The PSN is designed to be very energy efficient so that it can operate continuously for many years when powered by a 3.6 Volt battery or virtually indefinitely on a harvester.
The actual amount of power consumed (and therefore the effective battery life) is dictated by two factors:
- The frequency at which the sensor sends a heartbeat ping to the PRN, and
- The frequency at which the sensor collects and transmits vibration data to the PRN.
The heartbeat ping takes very little energy so the primary driver of battery life is governed by the vibration data collection frequency which you configure based on your business needs. The graph below illustrates how battery life varies with changes to collection frequency assuming the sensor heartbeats every four seconds.
