As duct static pressure increases the supply fan speed reduces.
Johnson controls duct static pressure sensor.
Johnson controls pressure control module.
The a 308 should be used only where accuracy is not critical.
Kele carries duct static pressure sensors and pressure accessories to fit your specifications.
Two sensors are required to monitor pressure across coils filters blowers etc.
All electric ddc duct static pressure control the controller uses a static pressure sensor located in the supply duct at the end of the longest run to modulate the supply fan to control duct static pressure.
Hvac field controls devices.
These sensor are normally used in conjunction with the vav 1000 2000 and 3000 series vav terminal controllers for individual zone control in hvac systems.
Static pressure sensors the a 300 series sensors are used with pressure transmitters and pressure switches to sense duct pressures.
Integrated fire security.
With over 1 8 million parts in stock kele makes it easy to avoid project delays.
Cooling capacity 20 25 22 4 56 kw utopia vrf.
The dpt 2015 is available mounted to an m9104 or m9106 electric non spring return actuator or to the johnson controls vav controller for reliable damper positioning in closed loop applications.
Choose from our humidity sensors hvac temperature sensors pressure sensors carbon dioxide sensors occupancy sensors and network sensors all designed with advanced technology to deliver the.
Wall or din rail mounting.
Duct high static pressure rpi fsn3 p e.
The dpt 2015 may also be mounted alone as an independent pressure transmitter or used for damper positioning in other vav systems.
Our control sensors aren t just engineered for performance they re engineered to help reduce expenses and time spent on installation.
Duct medium static pressure rpi fsn4e.
The h port senses total pressure and the l port senses static pressure the difference between these signals is differential or velocity pressure.
The p352 pressure controller is an automatic reset electronic pressure control with spdt relay output and led indication.
A 301 and a 302 have four radial sensing holes and 4 10 2 cm insertion depth.
The p352 is designed with a selectable direct reverse switch adjustable differential and replaceable pressure transmitters.
The units are ideal for hotel bedrooms banks and small offices where very low noise levels are needed.
