Selection and optional specifications

1. Model suffix code (core selection dimension)

Example explanation of selection dimension code

The output signals D (BRAN), J (HART 5/7), and Q (1-5V HART) determine the communication protocol and signal type

Capsule types F, L, M, H, V determine the range of measurement

Wet end materials S, L, H, M, etc. are suitable for different corrosive media

Explosion proof certification FF1 (FM explosion-proof), KS21 (ATEX intrinsic safety), CF1 (CSA explosion-proof) and other suitable for hazardous environments

2. Key optional functions

High precision (HAC): Improve the accuracy of M/H/V capsules.

High pressure structure (HG): MWP increased to 25MPa.

Lightning protection (A): Maximum withstand current of 6000A (1 × 40 μ s).

Anti corrosion treatment (X2/HC): epoxy coating or 316 stainless steel external parts.

Certificate type (L4/L5/L6/L9): Provide calibration certificates (including traceability, standard list, etc.).

Installation and ordering information

1. Installation points

Size: Different installation methods (vertical/horizontal/bottom/universal flange) correspond to different sizes (unit: mm/inch), please refer to the dimension diagram in the document, for example, the total length of the vertical pipeline type is about 223-256mm.

Wiring: 4-20mA type needs to distinguish between power/output terminals and external indicator terminals; The 1-5V type requires distinguishing between power terminals and signal terminals, and supports 3-4 wire connections.

2. Clear information required for ordering

Model, suffix code, and option code.

Calibration range (LRV/URV, -32000 to 32000, LRV needs to be 0 for square root output) and units (such as kPa, psi).

Output mode (linear/square root) and display mode.

The display scale of the integrated indicator (0-100% or custom range).

HART protocol version (choose 5 or 7 for J code).

Tag (TAG NO: 16/22 characters; Software Tag: 32 characters, HART 7 supports long tags).

Compliance and Reference
