Accuracy

INPUT TO POINTER
±0.5% of span for qualified elements.
INPUT TO OUTPUT
Depends on measuring element used.

Repeatability

0.2% of span.

Deadband

0.1% of span.

Ambient Temperature Effect

Maximum control point shift at midspan per 55°C (100°F) change within normal operating conditions is 1% of input span.

Supply Pressure Effect

Maximum control point shift at midspan per 7 kPa (1 psi) change within normal operating conditions is 0.2% of input span.

FUNCTIONAL SPECIFICATIONS

Elements

Refer to Measuring Element Specifications section for types, materials, and ranges.

Controller Action

Output signal either increases or decreases with in creasing measurement, as specified; action is reversible in the field.

Output Signal

20 to 100 kPa, 3 to 15 psi, or 0.2 to 1.0 bar or
kg/cm2, as specified.

Air Consumption (Under normal operation)

0.5 m3/h (0.3 cfm) at standard conditions.

Output Gauge

0 to 200 kPa, 0 to 30 psi, or 0 to 2 bar or kg/cm2, as specified.

Set Point Adjustment

By means of a knob mounted inside the case.

Pointers

Set point and measurement pointers are fluorescent red.

Scale

Black markings on white background; sector-shaped with nominal effective length of 150 mm (6 in). (Refer to Chart and Dial Catalog 600 for  vailable ranges.)

Connections (Located in Bottom of Case.)

PRESSURE AND VACUUM
? For upper range-values up to 14 MPa (2000 psi,
or 140 bar or kg/cm2): Connections tapped for
R1/4 or 1/4 NPT, as specified.
? For upper range-values from 14 MPa (2000 psi,
or 140 bar or kg/cm[sup/2]) up to 70 MPa
(10 000 psi, or 700 bar or kg/cm2): Connections
threaded for R1/2 or 1/2 NPT, as specified.
? For upper range-values above 70 MPa (10 000 psi, or 700 bar or kg/cm2): 9/16-18 Aminco? fitting used.
PNEUMATIC
Supply and output connections tapped for 1/4 NPT.

Mounting

PANEL
Flush in a panel up to 16 mm (0.6 in) thick.
SURFACE
Suitable for all controllers having internallymounted elements. Note that this mounting is not available with heavy duty helical elements. (These elements extend through the back of the case.)
PIPE
A kit of parts to fit a DN 50 or 2 in vertical pipe.
YOKE
Kit of parts to fit a vertical DN 50 or 2 in pipe stub. This mounting scheme is designed specifically for controllers having rear-mounted differential pressure elements.

PHYSICAL SPECIFICATIONS

Enclosure

The case is a glass fiber reinforced polyester molding, compounded for superior corrosion
resistance. The door is glass fiber reinforced phenylene oxide, and has a shatterproof polycarbonate window, ultraviolet resistant. The overall construction is weatherproof, meets IEC IP53, and provides the environmental protection of NEMA Type 3.

Finish

Case, gray polyester; door, blue textured polyurethane.

Data Label

Aluminum data label fastened to inside of door with pressure sensitive adhesive. Includes space for Customer Tag data up to a maximum of 72 characters and spaces. For additional space, see optional Customer Tag.

Approximate Mass

4.8 kg (10.6 lb), excluding element.
