Duct Static Pressure Sensor Johnson Controls

Our control sensors aren t just engineered for performance they re engineered to help reduce expenses and time spent on installation.

Duct static pressure sensor johnson controls.

High input low input and supply output. The p352 pressure controller is an automatic reset electronic pressure control with spdt relay output and led indication. 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. An optional discharge air static high limit reduces the fan speed if discharge static pressure increases above its setpoint.

The a 308 should be used only where accuracy is not critical. Consult johnson controls application engineering for specific information if a question regarding a specific application arises. 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. The btc02 control sequence may be found on drawing number 16777.

It sends an analog signal that is proportional to velocity pressure to a vav controller. As duct static pressure increases the supply fan speed reduces. Bypass terminal bpv. On a call for full pressure the fan runs at full speed.

Operation there are three connections on the p 5217. The dpt 2015 differential pressure transmitter senses differential pressure in pressure independent variable air volume vav 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 controller consists of the etdd6v static pressure control board the dwyer a 302 static pressure sensing probe and a duct mounted control enclosure.

A 301 and a 302 have four radial sensing holes and 4 10 2 cm insertion depth. Duct static pressure control building pressurization a typical system 350 static pressure control scheme. Two sensors are required to monitor pressure across coils filters blowers etc. For example end of duct run or fan discharge segments of an air distribution system.

The p352p static pressure controls are not typically used with staging modules. At johnson controls we ve designed our hvac sensors to work seamlessly within your hvac system. With over 1 8 million parts in stock kele makes it easy to avoid project delays. Static pressure sensors the a 300 series sensors are used with pressure transmitters and pressure switches to sense duct pressures.

Johnson controls pressure control module. A signal proportional to the measured static differential is transmitted to an indicator recorder or receiver controller. The p352 is designed with a selectable direct reverse switch adjustable differential and replaceable pressure transmitters.
