Abstract: A room condition monitor (RCM) that includes a processor with an embedded router software object that is in signal communication with a first communication connector including an interface for the transmission receipt of data packages over a building management system (BMS) communication network according to a first network protocol. A second communication connector with a second network protocol interface is provided for communication with network legacy devises (I/O devices) through the RCM router according to a second network protocol.

Abstract: A room condition monitor (RCM) that includes a processor with an embedded router software object that is in signal communication with a first communication connector including BACnet/IP interface for the transmission receipt of data packages over a building management system (BMS) communication network according to a BACnet/IP protocol. The RCM also includes a room condition sensor for detecting a room condition. In addition, the RCM includes a projected capacitive LCD screen display to display information regarding the detected room condition, or other building information associated with the BMS. A second communication connector with a second network protocol interface is provided for communication with network legacy devises through the RCM router.

Abstract: A system for controlling pressure associated with a volume may comprising a pump and piston/cylinder assembly, both in fluid communication with a volume of a closed fluid system. In addition, the system may comprise an actuator operatively connected to the actuator and pump to control fluid flow and pressurization or depressurization of the volume and/or fluid flow system. The pump is activated to generate a first pressure level of the closed fluid system and when this first pressure level is reached the actuator is activated to drive the piston/cylinder assembly to reach a pressure set point from the first pressure level. The system may be used as a calibrator or a pressure controller for pressure differentials, gauge pressure or absolute pressure.

Abstract: A pressure monitoring apparatus (10) including features that simplify in-situ calibration procedures. A pressure monitoring module (12) of the apparatus is coupled to external pressure lines (14, 16) and an external electrical interface (24) via an easily removable monitoring module plug (32). The monitoring module can be disconnected from the pressure lines and external interface and then connected to a portable calibration module (42) by simply replacing the monitoring module plug with a calibration module plug (50). The calibration module plug provides an electro-pneumatic interface between the monitoring module and the calibration module. The monitoring module may be electronically interrogated and automatically calibrated via a processor of the calibration module. The monitoring module plug may be inserted onto the calibration module plug to provide actual system pressures to the now-calibrated apparatus for final documentation.

Abstract: An apparatus (10) for sensing a condition, such as humidity, through an opening (20) in a surface (12) such as a duct or wall. A housing (14) includes an outer section (16) mounted on the surface and a probe section (18) extending into the duct or wall. A circuit board assembly (32) is mounted within the housing and includes a user interface section (34) within the housing outer section and a sensor section (36) rigidly connected to the user interface section and extending into the housing probe section. The sensor section may be integrated into the circuit board assembly by a rigid connector (42) allowing easy removal and field replacement of the sensor section. A sealing device (56) isolates the housing outer section from the air within the duct or wall. A flexible grounding connection (66) provides electrical grounding of the circuit board assembly and a degree of mechanical support.
