Pressure switch and Thermostat Type KP and KPI
Data Sheet Pressure switch and Thermostat Type KP and KPI For industrial applications The KP and KPI pressure switches and thermostats are used for control, monitoring and alarm systems in a wide variety of industry applications. KP pressure switches are mainly used for gaseous fluid whereas KPI pressure switches are more for liquid and gaseous fluid. The products are available in IP30 enclosure as well as IP55 enclosure. The KP pressure range include special designed pressure switches and limiters for steam boilers and other heating applications. For water pump control and protection (dry run) the dual pressure switch KP44 is suitable and secure improved life time of the water pump.

This means that the bellows is active only when the cut-in or cut out value is reached. The bellows is connected to the pressure of the controlled plant via the connector. Danfoss KPI pressure switches are designed so that the bellows moves in the same proportion as the pressure switches change. To ensure a snap function on contact change over, an omega spring is located between bellows and contact system. © Danfoss | Climate Solutions | 2022.05 AI000086439001en-001001 | 3 Pressure switch and Thermostat, Type KP and KPI KP 44 pressure switch Figure 4: Key sketch of KP 44 pressure switch Danfoss 60-1175.12.10 O=14mm 1 Lefthand pressure setting spindle 2 Differential setting spindle 3 Main arm 4 Righthand pressure setting spindle 5 Main spring 6 Differential spring 7 Bellows 8 Pressure connections 9 Contact system 10 Terminal 11 Earth terminal 12 Cable entry 13 Tumbler 14 Locking plate 15 Impulse lever Water supply from reservoir or well The contact system in the KP 44 has a snap-action function and allows the bellows moves only when the cut-in or cut-out value is reached. If water is running short in the well or reservoir, the pump will no longer be able to increase the pressure to the cutout value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pressure switch will stop the pump as soon as the righthand bellows pressure drops below the safety cut-out setting. The pump can be started again by lifting the impulse lever. The pump will continue to operate when the impulse lever is released, provided that the righthand bellows pressure is higher than the safety cut-out setting plus a fixed differential of 1 bar. If this is not the case, the pump will cut-out again indicating insufficient water supply. Pressurized water supply direct to pump When water supply fails on the inlet side, the pump will no longer be able to boost the pressure to the cut-out value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pressure switch will stop the pump as soon as the pressure in the pump suction line drops below the safety cut-out setting. The pump will automatically start again when the pump suction pressure has reached the level of 1 bar above the safety cut-out setting. Automatic start-up will only take place if the righthand bellows is connected to the pump suction line. Air pockets should be avoided to prevent the pump from starting up on air pressure rise, without the presence of water. © Danfoss | Climate Solutions | 2022.05 AI000086439001en-001001 | 4 Pressure switch and Thermostat, Type KP and KPI In a hydrophore system where water is pumped from a well or an open tank, both bellows are connected to a pressure outlet on the air side in the pump pressure line, if possible. In a booster system receiving pressurized water the righthand bellows is connected · to the low pressure side of the pump forautomatic start-up · to the high pressure side of the pump for manual start-up The lefthand bellows is always connected to the high pressure side of the pump.

The cut-out pressure must be above absolute vacuum (pe = -1 bar). For high pressure switches the restart pressure is equal to cut-out pressure minus differential. Pressure switches with manual reset Set the cut-out presure on the "CUT-OUT" scale (range scale). High pressure limiters can be manually reset when the pressure is equal to the stop pressure minus the differential. NOTE: For low pressure switches the restart pressure is equal to cut-out pressure plus differential value.

Automatic start-up, if any, will take place when the pressure has reached the level of 1 bar above the setpoint. Manual cut-in is made by lifting the impulse lever and releasing it again when the pressure has increased by min. 1 bar. The safety cut-out setpoint is normally determined by the static pressure (the water column). However, in order to avoid disturbing signal interaction, care should be taken to ensure that the safety cut-out setting is at least 1.5 bar lower than the control pressure cut-in setting.

The solid substance is concentrated in the sensor, and consequently it is always the sensor that comprises the temperature-regulating part of the thermostatic element. The sensor can be placed both warmer or colder than the thermostat housing and capillary tube. However, placing it in an ambient temperature higher or lower than 20 °C can affect the accuracy of the scale. © Danfoss | Climate Solutions | 2022.05 AI000086439001en-001001 | 9 Pressure switch and Thermostat, Type KP and KPI Setting Thermostats with automatic reset Set the upper limit temperature on the range scale. Then set the differential on the DIFF scale. The temperature set on the range scale is also the temperature at which contact changeover re-occurs on rising temperature. The contacts changeover when the temperature has fallen to a value lower than that set on the DIFF scale. If at lower settings the plant will not start/stop, the reason might be that the differential has been set too high. Thermostats with minimum reset Set the temperature on the range scale. The differential setting is fixed. Min. reset units will restart after the temperature at the thermostat sensor has risen by a value greater than that of the fixed differential. Thermostats with maximum reset Set the stop temperature on the range scale. The differential setting is fixed. Max. reset units will restart after the temperature at the thermostat sensor has fallen by a value greater than that of the fixed differential.

Differential The difference between contact changeover on rising and falling pressure. The differential is a condition for stable automatic plant operation. Manual reset A unit with manual reset can only be restored to operational mode by activation of the external reset button. Min. reset units will restart after the pressure has risen by a value greater than that of the fixed differential. Max. reset units will restart after the pressure has fallen by a value greater than that of the fixed differential. Automatic reset Units with automatic reset restart automatically after stop. Permissible operating pressure The highest permissible constant pressure or pressure variation the unit can be exposed to. Maximum test pressure The maximum pressure applied in strength or leakage tests on heating system or components thereof. Maximum working pressure The maximum permissible pressure for safe functioning of a heating system or any of its parts. Snap function A specific contact force is maintained until snap is initiated. The time over which contact force reaches zero is a few milliseconds; therefore, contact bounce cannot occur as a result, for example, of slight vibrations before cut-out. The snap-action contact system will continue to function even when micro-welds are created between the contacts during cut-in. The force created to separate the contacts is strong, and instantly shears off all contact surface welds that have been created as the result of cut-in action. These design features ensure that the cut-out point of the KP control remains very accurate and completely independent of the magnitude of the current load.
