Foxboro-IAP10-IA-Differential-Pressure-Transmitter

Foxboro-IAP10-IA-Differential-Pressure-Transmitter

DESCRIPTION

The Foxboro® brand Models IAP10, IGP10, IAP20, IGP20, and IDP10 are low power, voltage output  transmitters that provide precise, reliable measurement of gauge, absolute, and differential pressure, draw  no more than 3 mA, and transmit a 1 to 5 V dc output signal.

LOW POWER DESIGN

When you need a low power, low voltage transmitter,  these I/A Series Pressure Transmitters deliver:

 1 to 5 V dc Output Signal 

 9 V dc Minimum Voltage 

 3 mA Maximum Current

EXTENSIVE LINE

Unsurpassed breadth of line for measurement  types, materials, and process connections. Can also  be provided with direct connect or capillary  connected pressure seals, and industry specific  seals for sanitary, and pulp and paper processes.  The line also includes a selection of traditional or low  profile differential pressure transmitters.

CERTIFICATIONS

 Transmitters meet numerous Agency  requirements for hazardous area locations.  Versions available to meet Agency flameproof  and zone requirements. 

 Dual Seal certified to meet  ANSI/ISA 12.27.01-2003 requirements.

HIGH DEPENDABILITY

 Silicon strain gauge sensors successfully fieldproven in hundreds of thousands of installations. 

 Standard 5-year warranty

Adjustable Damping

Transmitter response time is normally 0.75 s, or the  electronically adjustable setting of 0 (none), 2, 4, or  8 seconds, whichever is greater, for a 90% recovery  from an 80% input step as defined in ANSI/ISA  S51.1. (For 63.2% recovery, 0.50 s with sensors B to  F, and 0.60 s for sensor A.)

European Union Directives

 Complies with Electromagnetic Compatibility  Requirements of European EMC Directive  2004/108/EC by conforming to the following EN  and IEC Standards: EN 61326-1, and  IEC 61000-4-2 through 61000-4-6. 

 Complies with NAMUR NE 21 Interference  Immunity Requirement, and NAMUR NE 43  overrange and underrange annunciations. 

 Conforms to Applicable European Union  Directives (“CE” Logo marked on product).

Electronics Housing and Housing Covers

Housing has two compartments to separate the  electronics from the field connections. The housing  and covers are made from low copper (0.6%  maximum) die-cast aluminum alloy with an epoxy  finish, or from 316 ss. Buna-N O-ring seals are used  to seal the threaded housing covers, housing neck,  and terminal block.

Electrical Terminations

Field wires enter through 1/2 NPT, PG 13.5, or M20  threaded entrances, as specified, on either side of  the electronics housing. Wires terminate under  screw terminals and washers on terminal block in  the field terminal compartment as shown in Figure .  Unused threaded field wire entrance is plugged to  insure moisture and RFI/EMI protection.

Three- or Four-Wire Connections

Transmitter is supplied with a 4-wire terminal block,  with the two negative terminals connected internally.  This means that the transmitter can be wired with  either three wires for wiring economy, or four wires  for maximum accuracy. For relatively short wiring  runs having low resistance, 3-wire connections can  be used to minimize wiring costs. However, a voltage  drop in the common lead carrying the power supply  current will cause an error in the 1 to 5 V dc signal.  For wiring runs with high resistance due to long  lengths (or other reasons), or for maximum  accuracy, a 4-wire connection may be used to  provide input-output isolation. With 4-wire  configurations, voltage drop in the power supply loop  will have minimal effect on measurement.
