Optional LCD Display, Replaceable Sensors

The Series RHP-W Wall Mount Temperature/Humidity/Dew Point Transmitteris the most versatile room transmitter on the market. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy.

An optional LCD display can be integral to the transmitter or a remote display can be ordered for building balancing or LEED® validation.

The LCD display indicates the ambient temperature along with the humidity or dew point. The transmitter has internal dip switches to select the temperature engineering units and whether the transmitter outputs humidity or dew point.The humidity and temperature sensors are field replaceable to reduce service cost and inventory.

The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD or thermistor.

Thermistor or RTD For models with current or voltage for the temperature output, the temperature range is field selectable.

Rectangular, Oval or Circular Configurations

The Series FLST Airflow Measurement Stationis easy to install – simply connect the tubing to the station fittings, then to a differential pressure manometer, gage, transmitter or switch. Single or multiple airflow elements are factory mounted and pre-piped in a casing designed for flanged connection to the ductwork. Standard materials consist of a G90 galvanized casing and 6063- T5 anodized aluminum flow sensors, suitable for most HVAC applications.

The Series FLST utilizes an airflow averaging element in a head-type device, generating a differential (velocity) pressure signal similar to the orifice, venturi,and other head producing primary elements. Strategically located sensing ports continually sample the total and static pressures when inserted normal to flow.

Total pressures sensed by the upstream ports are continually averaged withinthe airflow element in an isolated chamber. The static sensing ports are averaged in a second isolation chamber. Multiple elements are joined together for connection to a differential measurement device (gage, transmitter, etc.) forflow measurement and indication purposes.
