These instructions provide information for installation, electrical connection, process con-

nection and calibration of 102 Differential Pressure Detectors.

Process pressure is sensed by a piston assembly. The piston responds to differential

pressure and moves a lever connected to a torsionally stiff cross-shaft. One end of the

cross-shaft is connected to a lever that is biased by the range spring. The other end has a

lever that actuates (deactuates) an electrical detecting element.

Installation

Use care during installation not to inadvertently move the electrical

detectng element or t’s housng. Movement of ether could dsturb the

relative positions of internal working parts and alter factory-set calibration or

render the device inoperative.

This product should be installed by trained and competent personnel only.

Ensure that all wiring conforms to all applicable local and national electrical codes and

install unit(s) according to relevant national and local safety codes.

Securely mount a pipe kit bracket or base plate as supplied to horizontal member of the

pipe stanchion, channel rack or a flat surface using suitable bolts. The 102 is not position

sensitive, and may be mounted in any position.

Process Connection

The high pressure side (marked Hi) and the low pressure side (marked Lo) have 1/4”

NPT(F) process connections (1/2” NPT(F) optional).

When the process could be considered dirty in terms of suspended particles,

it is recommended that 20-micron in-line lters be installed on the Hi and Lo

pressure ports.

Electrical Connection

Weathertight Models:

Interrupt the electrical power. Remove the top cover plate. The terminal block is standard,

except with B, BB, W or Y high-temperature detecting elements. The insulation is labeled

C - Common, NO - Normally Open, NC - Normally Closed and C2, NO2, NC2 when 2-SPDT

detecting elements are installed.

Explosion Proof Models:

Units in hazardous locations: prior to removal from service, make sure that the

work area is declassied. Failure to do so could result in severe personal injury

or substantial property damage.

The hermetically sealed detecting element capsule has 18” - 18 AWG wire leads color

coded and marked C - Common, NO - Normally Open, NC - Normally Closed, and G -

Ground (earth) when applicable. When 2-SPDT detecting elements are installed, additional

wires are marked C2, NO2 and NC2. (See schematic.)

Safety Integrity Level (SIL) Installation Requirements

The SOR pressure detectors have been evaluated as Type-A safety related hardware.

To meet the necessary installation requirements for the SIL system, the following

information must be utilized:

Proof Test Interval shall be one year.

Units may only be installed for use in Low Demand Mode.

Products have a HFT (Hardware Fault Tolerance) of 0, and were evaluated in a



The terminal box to which the equipment is attached must, together with the detector,

ensure the requisite thread engagement for Apparatus Group IIC. AD Housing: ATEX

Approved junction box required.



The permanently attached cables are to be suitably terminated and protected from

impact.



When the detector is attached to an increased safety terminal box, the assembly must be

capable of withstanding the impact test specified in BS 5501: Part 1: 1997.



The sealing arrangements must maintain the minimum IP54 rating required by the

increased safety enclosure.



The detector must attach to the enclosure using an existing entry.

The apparatus may have a combined nameplate which carries multiple approvals

(Intrinsic Safety & Flameproof). The equipment should be marked as to which

protection method it is installed as, and shall not be changed or utilized in any

other manner than was originally marked by the end user.

To minimize the risk of electrostatic discharge, clean only with a damp cloth.

NOTE: These circuits are all part of the same IS circuit meeting the requirement of 30V max

and 1A max. You cannot connect a zener barrier to C/NO/NC circuit and another barrier to

C2/NO2/NC2 circuit unless the combination of the two barriers is intrinsically safe and is

less than 30V and 1A.

NOTE: For IS, there must be no connection to GND if the detector circuit is connected to a

shunt zener diode safety barrier.

Calibration

Coarse Calibration:

Device calibrated without reference to system (static) pressure (Lo side vented).

Test apparatus: Pressure gauge

Variable pressure source

Test light or ohmmeter

1. Remove the weathertight knurled cap.

2. Insert a 5/32 Allen hex wrench into Set Point adjustment screen.

3. Connect a test light or ohmmeter to C – Common and NO – Normally Open.

4. Increase the pressure to the desired Set Point on increasing pressure.

5. Turn the hex wrench clockwise to increase the Set Point and counterclockwise to

decrease the Set Point. Note the actuation/deactuation by test light or ohmmeter.

6. For the Set Point on Decreasing pressure, decrease the pressure to the desired Set

Point and repeat Step 5.

7. Remove the hex wrench and replace the weathertight cap.

Precise Calibration:

The device is calibrated with reference to system (static) pressure. Performance is

enhanced when calibration is accomplished under simulated system pressure profile or as

it is intended to be used in actual service.

Test apparatus: Differential pressure gauge

Variable pressure source

Block/bleed and equalizer valves

Test light or ohmmeter

1. Remove the weathertight knurled cap.

2. Insert a 5/32 Allen hex wrench into the Set Point adjustment.

3. Connect a test light or ohmmeter to C – Common and NO – Normally Open.

4. Increase the pressure equally on Hi and Lo sides to the desired system (static) operating

pressure (equalizer valve open).

5. To adjust Set Point on Increasing Differential Pressure: Close the equalizer valve and

bleed the Lo side until the desired pressure appears on indicator and the Set Point is

verified by a test light or ohmmeter. Turn the hex wrench clockwise to increase the Set

Point and counterclockwise to decrease the Set Point. Note actuation/deactuation by

test light or ohmmeter.

6. To adjust the Set Point on Decreasing Differential Pressure: Differential Pressure must be

at or above the Increasing Set Point. Slightly open the equalizer valve until desired

decreasing pressure appears on the indicator and the set point is verified by a test light

or ohmmeter. Perform Step 5 above as necessary.

7. Remove the Allen wrench and replace the weathertight cap.

Do not remove other covers or attempt to adjust other parts of the mechanism. All

have been precisely positioned at the factory and should not be moved in the eld.
