Differential Low Pressure Sensors

Description

Based on inductive sensing (LVDT), it can be used to:

• monitor the pressure difference to between premix fan and gas valve output
• detect blockage in gas combustion system
• detect correct fan operation
• detect a blocked filter measuring a pressure drop

Main features

• Customized mounting bracket (on request for quantity)
• Flow restricted orifices

Flow Sensors

Description

• This device detects the water flow rate into the DHW circuit.
• The rotation of the impeller is detected by a reed switch or a Hall sensor
• The rpm of the rotor is proportional to the flow rate through a constant K factor.

High Pressure Sensors

Description

A high pressure inductive sensor (LVDT) to be connected to the CH circuit.

Main Features

• Calibration: custom output characteristic, calibrated in several points over the range
• Autozero: no autozero is required to get the specified performances
• PWM, Voltage and Frequency Output
• Double Insulation
• Snap fit mounting

Temperature Sensors

Description

• The TR-300 is a temperature sensor for direct measurement by immersion in the medium.
• Compared to contact sensors, immersion sensors offer advantages in terms of response time and accuracy of the measure.

Main features

• NTC sensor
• Quick response (5 s max) and high accuracy
• Wide temperature range
• Custom models available (for quantity)
• Steel clip with o-ring seal
