RW65 Ringbalance Differential Pressure Indicator

Overview

Ranges from 0-40 Pa up to 0-1.8 kPa.

Specifications

Low-pressure indication

Selectable ranges from 0…40 Pa to 0…1.8 kPa

Analogue display

Large 150 x 150 mm scale for clear local reading

Multiple duties

Measures draft, pressure, differential pressure and flow

Contact options

Inductive or mechanical contacts available for switching duties

Industrial housing

IP65 wall-mounted enclosure with hardened front glass

Overload option

DZ overload protection available where pressure spikes may occur

Ringbalance measuring principle

Provides stable local indication for low draft, pressure, differential pressure and flow measurement in gaseous media.

Application-specific range selection

Freely selectable measuring ranges allow the RW65 to be matched to low-pressure duties from 0…40 Pa to 0…1.8 kPa.

No electrical supply required

Mechanical local indication supports pressure reading at the instrument without a dedicated power supply.

Flexible scale configuration

Scale units can be specified in Pa, kPa, daPa, mbar, mmWS, mmCE or in.W.C. to suit site standards.

Optional inductive contacts

NAMUR / ATEX inductive sensors can support minimum, maximum, dual minimum or minimum / maximum switching functions.

Optional mechanical contacts

Mechanical contacts are available for measuring ranges above 200 Pa where simple switching is required.

Industrial wall mounting

IP65 glass-reinforced polycarbonate housing with hardened front glass supports use in demanding plant environments.

Overload protection option

DZ overload protection can be specified where pressure spikes or abnormal overload conditions may exceed standard limits.

Range selection

Support selecting the appropriate measuring range and scale unit for the application

Overload protection
