With over 1 8 million parts in stock kele makes it easy to avoid project delays.
Duct static pressure sensor johnson controls.
A signal proportional to the measured static differential is transmitted to an indicator recorder or receiver controller.
Consult johnson controls application engineering for specific information if a question regarding a specific application arises.
At johnson controls we ve designed our hvac sensors to work seamlessly within your hvac system.
As duct static pressure increases the supply fan speed reduces.
Johnson controls pressure control module.
It sends an analog signal that is proportional to velocity pressure to a vav controller.
Wall or din rail mounting.
Duct static pressure control building pressurization a typical system 350 static pressure control scheme.
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.
Bypass terminal bpv.
The p352 pressure controller is an automatic reset electronic pressure control with spdt relay output and led indication.
Duct static pressure transmitter.
High input low input and supply output.
For example end of duct run or fan discharge segments of an air distribution system.
Two sensors are required to monitor pressure across coils filters blowers etc.
An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint.
Kele carries duct static pressure sensors and pressure accessories to fit your specifications.
Our control sensors aren t just engineered for performance they re engineered to help reduce expenses and time spent on installation.
Static pressure sensors the a 300 series sensors are used with pressure transmitters and pressure switches to sense duct pressures.
The p352p static pressure controls are not typically used with staging modules.
Operation there are three connections on the p 5217.
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.
The mamac systems model pr276 duct static pressure transmitter incorporates sophisticated integrated circuits and a new micro machined glass on silicon gl si capacitance sensor to not only provide a high level fully conditioned and temperature compensated output but also to offer up to three 3 field selectable pressure ranges in one unit.
The btc02 control sequence may be found on drawing number 16777.
On a call for full pressure the fan runs at full speed.
The btc02 controller consists of the etdd6v static pressure control board the dwyer a 302 static pressure sensing probe and a duct mounted control enclosure.
The dpt 2015 differential pressure transmitter senses differential pressure in pressure independent variable air volume vav applications.
