Reference sensor for HVAC applications where compensation of solar radiation is required or desired
Repositioning Blinds / Lighting Controls, Solar compensation for Heating / Cooling Applications
Feature
Function
Benefit
Small compact housing
Easy handling
Enables flexible mounting locations
NEMA 4 equivalent rating
Sealed with a gasket to keep out rain and moisture
Promotes outside mounting without damaging internal photo measurement cell
0-10 Volt or 4-20mA (selectable) output
Provides signal to controller
Linear over the measured solar radiation range
Output does not have to be converted from a sinusoidal function
Standard outputs, provides flexibility depending on controller input type
True air flow measurement
Mounting flange
Secures the sensor to the ductwork
Allows the installer to vary the probe insertion length into the duct space for best control
Mounting flange dampening gasket
Minimizes vibration to the sensor
Enables sensor to stay firmly mounted
Graduated probe
Measures insertion length
Ensures maximum flow accuracy
Flow directional arrow
Assures correct probe orientation
Provides an accurate flow reading
Connection cable
Housing-to-probe electrical connection
Flexibility in mounting
Jumper selectable flow range
Field adjustable flow ranges
Application flexibility
Demand-controlled ventilation of wet zones: This saves energy, and prevents damage resulting from humidity.
Booster pumps: Pumps activated in accordance with demand deliver the water pressure called for by the system.
Protection against dry-running: Motors are switched off when there is no flow.
Instantaneous District HW heaters: The heater is switched on when the water tap is opened.
General use: Independent monitoring of liquid flows in HVAC facility.
Detachable steel paddles (4)
Used for measuring flows in different pipe sizes
Provides correct flow measurement based on pipe diameter
Adjustment screw
Sets switching threshold
Allows switching point to be varied based on flow rate
Single part number
Handles multiple line sizes
Easier for product selection/ordering
Flexible, trim-able paddle
Used for measuring flows/triggering based on flow rate in different pipe sizes.
Using a small pair of pliers, the length of the paddle can be easily shortened to the required size.
Provides correct flow measurement based on pipe diameter without multiple paddle components.
No more need for making bothersome adjustments with screw drivers and sheet metal.
Contact-free reed switch
No reset spring.
No aging or fatigue on the mechanical components.
Stable switching points and insensitivity to dirt and icing
Compact size and light weight
Simplifies mounting
Useful for confined spaces where access is restricted
Glass fiber-reinforced plastic paddle
De-zincification is impossible
Avoids paddle rupture that can occur with sheet steel paddles that are exposed to poor water quality over longer periods of time
Gives paddle rigidity
Resistant to scale deposits, unlike steel paddles
