Intelligent Differential Pressure Transmitter IDP31
The I/A Series System differential pressure transmitter IDP31 is a microprocessor-based smart transmitters that provide precise, reliable, measurement of differential pressure, and features high performance and excellent stability. Capable of measuring gas, liquid, vapor, and liquid levels, it transmits 4 to 20mA dc analog and digital signals according to the measured differential pressure. It can also execute two-way communications using HART protocol, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment
Unique characterization and composite semi- conductor sensors realize high accuracy up to 0.04% F.S.
Proven Sensor technology enables Long-term stability up to 0.1% of URL per 10-year period.
- A wide measuring range is available from a single model. This feature is highly effective in taking measurement over a wide range and reducing the need for inventory.
- Model IDP31D and IDP32D: 0.5 to 100kPa (rangeability: 200 to 1).
- Two-way communication using HART protocol facilitates self-diagnosis, range resetting, automatic zero adjustment, and other operations.
- HART communication protocol.
- Complies with 89/336/EEC, 92/31/EEC, and 93/68/EEC Electromagnetic Compatibility (EMC) Directive.
- Complies with FM Explosionproof and Dust Approvals, FM Intrinsically Safe Approval, and FM Nonincendive Approval.
- Complies with ATEX Flameproof and Dust, ATEX Intrinsic safety and Dust, and ATEX Type n and Dust Certifications.
OIL FREE FINISH
The transmitter is shipped with oil-free wetted parts.
ADAPTERS FOR ANTICORROSION MATERIALS
These are adaptor flanges to connect 82 mm pipes made of anticorrosion materials [excluding ASTM B575 (Equivalent to Hastelloy C-276)] to 54 mm general-purpose pipes.
EXTERNAL ZERO/SPAN ADJUSTMENT FUNCTION
The transmitter can be easily zero/span adjusted in the field.
CONFORMANCE TO NON SI UNITS
We deliver transmitters set to any Non SI units as specified.
Select this option to be used as a component of Safety Instrument System (SIS). ECS Series Component Transmitters comply with IEC61508, certified according to Safety Integrity Level2 (SIL-2) when this option is selected.
ALARM OUTPUT (CONTACT OUTPUT)
Contact output is prepared as alarm output when alarm (Output Alarm/Sensor Temp. Alarm) condition is detected. It can be set to Normally Open. (When alarm is detected, Contact ON).
89/336/EEC, 92/31/EEC, 93/68/EEC Electromagnetic Compatibility (EMC) Directive.
PED CONFORMITY (97/23EC)
The maximum pressures applicable under the Sound Engineering Practice (SEP) section of the Pressure Equipment Directive depend on the type of fluids measured, as shown in Table 1. Devices in the ECS Series Component Differential Pressure Transmitters shall be used at or below the applicable pressure in the table or the device's maximum working pressure, whichever is lower. Any ECS Series Component Pressure Transmitter model having a maximum working pressure that is higher than the pressure corresponding to its group does not conform to SEP and cannot be used. To know more about maximum pressures that are applicable for gases and liquids, contact us.
