Pressure transmitter
Measuring and transmitting pressure plays a key role in system monitoring and controlling pumps/fans in order to achieve a required pressure at any given time
Pressurised pumping stations
Pressurised pumping stations
Profibus
PROFIBUS is a network technology mostly used in process industries but you can find it also in building automation. It is a standardised technology for data communication, managed by Profi International.
Proportional pressure, calculated - control mode
Proportional pressure is used in circulation systems with a pipe system with low pressure loss and control valves to generate a variable flow.
Proportional pressure, measured - control mode
Proportional pressure is used in circulation systems with an exten­sive pipe system and control valves to generate a variable flow.
PT 100 sensor
A PT 100 sensor is a temperature sensor which works by measuring electrical resistance through platinum (Pt) metal. A PT 100 sensor can measure temperatures up to 600 °C
PTC thermistors
Thermistors are resistors that react to temperature changes. Two categories exist: thermally sensitive silicon resistors and polycrystalline ceramic materials
Pump revolutions
Changing the revolutions of the pump to a lower or higher speed will change pump curve
Pumps in parallel
Pumps in parallel will increase Q
Pumps in series
Pumps in series will increase the head
