DPIL Liquid Differential Pressure Sensor

Cảm biến chênh áp

Description
The DPIL is suitable for measurement of differential pressures
across pumps, boilers, chillers, filters etc. in HVAC applications.
The use of thick film resistances fixed on a ceramic chip gives
no mechanical ageing or creepage. The sensor is loop-powered
giving a 4 to 20 mA signal equivalent to the measuring range.
Electrical connection is via a DIN (4350-A) IP65 connector
supplied) and pressure connections are screw compression
fittings for 6 mm pipe. It is supplied complete with a mounting
bracket.
Features
• Wide temperature range
• 4 to 20 mA output
• IP65 Housing

FUNCTIONALITY
The differential pressure is applied across a ceramic chip onto which are fixed thick film resistances. The ceramic chip is protected
from the medium by EPDM (Ethylene propylene) seals. The internal amplifier produces a 2 wire (loop-powered) 4 to 20 mA signal.
The pressure connections are screw compression fittings for 6 mm outside diameter pipes.
The electrical connection is via a DIN 43650-A connector with IP65 seal suitable for 11 mm (0.43”) outside diameter cable.

Input channel and sensor scaling
The input channel should be linked for loop powered current, I.
The sensor type module must be set up with the correct scaling.
The recommended method of setting the sensor type scaling is
to use SET. For all IQ2 series controllers with firmware version
2.1 or greater, or IQ3 series controllers, the appropriate SET
Unique Sensor Reference given below should be used.
Pressure I 0.5 bar
Pressure I 1 bar
Pressure I 2.5 bar
Pressure I 4 bar
Pressure I 6 bar
Pressure I 10 bar
Alternatively set scaling mode to 5 (characterise) and enter
scaling manually as defined in appropriate table below. Note that
for IQ3 the scaling mode and exponent (E) do not need to be
set up.
