ULTRAC RSP Room Pressure Sensor
Applications
The ULTRAC Room Static Pressure Sensor (RSP) is designed for accurate, smooth sensing of the actual static pressure within an enclosed space such as a laboratory, clean room, or other area.
The RSP Sensor senses average pressure changes at the exclusion of pressure waves created by moving objects or ventilation currents within the room. Precise pressure measurement and/or control of the room is possible when the RSP Sensor is used with a suitable pressure indicator or transmitter.
Installation
The RSP Sensor may be mounted on a ceiling, wall, or floor, and in any mounting position required. A ceiling mount near the center of the room, away from avoidable air currents, is the preferred location. Very large rooms may require multiple sensors with the tubing manifolded to provide an average.
Models are available with the pressure connection on the end or side of the cylinder-shaped device. The ceiling mount is designed with the pressure connection running through the mounting plate on the end of the cylinder. This design places the process tubing above the ceiling, out of sight.
Tall or short models are offered with aluminum or stainless steel materials.
Specifications for ULTRAC RSP
