The Type 500X is available in two different

versions. The lower range model is

designed for standard process control

applications which typically utilize a 3 to

15 psig output. The extended range unit

provides up to 120 psig output for higher

pressure industrial pneumatic and

process control system requirements.

Principle of Operation

The Type 500X Transducer is a force

balance device in which a coil is suspendedi

n the field of a magnet by af

lexure. Current flowing through the coil

generates axial movement of the coil

and flexure. The flexure moves towards

the nozzle and creates back pressure

which acts as a pilot pressure to an integral

booster relay. Input signal increases

(or decreases for reverse acting) cause

proportional output pressure increases.

Zero and Span are calibrated by turning

adjust screws on the front face of the

unit. Adjustment of the zero screw repositions

the nozzle relative to the flexure.

The span adjustment is a potentiometer

that controls the amount of current

through the coil.

Mounting

The Type 500X may be mounted by

pipe, panel, or bracket. Field adjustment

of the zero may be required if position is

changed. High external vibration may

cause output fluctuations. Mounting in a

vibration-free area is recommended.

Split Ranging

If split ranging is required the 4-20 mA

input, 3-15 psig output version

(ControlAir part number 500-AC) can be

recalibrated to provide a 3-9 psig or 9-

15 psig output.

Intrinsically Safe

The Type 500X has been tested and

approved by Factory Mutual as

Intrinsically Safe Class I, II, and III,

Division 1, Groups C, D, E, F and G

when used with an apparatus meeting

the following entity requirements:

Unit also meets the requirements of IEC

standards IP65.

Installation should be in accordance with

431-990-013. This drawing is included in

the Type 500X Installation, Operation and

Maintenance Instruction. The Intrinsically

Safe approval is a standard feature of the

Type 500X and applies only to units with

a 4-20 mA input signal that are installed

with the following barriers:

The Type 500X is also Factory Mutual

Approved as Nonincendive for Class I,

Division 2, Groups A, B, C and D, and

suitable for Class II and III, Division 2,

Group F and G. Barriers are not required

for nonincendive rating.

Field Reversible

In the reverse acting mode the output is

the opposite of the direct acting mode

(i.e. 4-20 mA input creates a 15-3 psig

output). To change from direct acting to

reverse acting simply reverse the polarity

of the signal leads and recalibrate. Input

signal failure causes output pressure to

reach maximum value (i.e. 15 psig)

when reverse acting.
