CPS491D Model Selection Table Overview
This article provides selection code descriptions for CPS491D, covering type, measuring rod length, additional options, certification, and tag (TAG). Engineering technical personnel and procurement can confirm item by item based on site conditions, installation dimensions, and explosion-proof requirements.
When selecting, first determine the type and measuring rod length, then select additional options and certification level; if a special version is selected, a TSP number must be provided. The tag is used to identify the instrument and can be defined in additional notes.
Type and Measuring Rod Length Selection
Type Code
| Feature | Code/Value | Description |
|---|---|---|
| Type | 7 | Basic type |
The basic type is suitable for conventional measurement scenarios. If another type is required, select the special type and define the TSP number.
Measuring Rod Length Code
| Feature | Code/Value | Description |
|---|---|---|
| Measuring rod length | 2 | 120 mm |
| 4 | 225 mm | |
| 5 | 360 mm | |
| 6 | 425 mm | |
| 9 | Special type, please define TSP number |
The measuring rod length should be selected according to the actual installation depth and process connection position. If the standard length cannot meet the requirements, select code 9 and define the TSP number.
Additional Options and Certification Options
Additional Options
| Feature | Code/Value | Description |
|---|---|---|
| Additional options | 2 | Perfluoro rubber |
| 9 | Special type, please define TSP number |
Perfluoro rubber is suitable for applications with high corrosion resistance or hygiene requirements. Special versions require a TSP number.
Certification Code
| Feature | Code/Value | Description |
|---|---|---|
| Certification | C | ***Non-hazardous area + EAC marking |
| G | **ATEX II 1G; FM IS NI; CSA IS NI Ex ia IIC T4/T6 Ga CL. I. DIV 1&2. GP A-D IECEx Ex ia IIC T4/T6 Ga | |
| K | **EAC Ex, 0Ex ia IIC T4/T6 Ga X | |
| 1 | ***Non-hazardous area | |
| 9 | Special type, please define TSP number |
Certification options directly affect whether the instrument can be used in explosive hazardous areas. G and K codes involve intrinsic safety explosion protection; when selecting, verify the area classification, gas group, and temperature class.
Tag (TAG) and Selection Steps
Tag Option
| Feature | Code/Value | Description |
|---|---|---|
| >>Tag | Z1 | Tag (TAG), see additional notes |
The tag is used for field identification and system mapping. When selecting Z1, please provide the tag text in the additional notes.
Recommended Selection Steps
- Confirm whether the application scenario requires explosion-proof certification; if required, preferentially select G or K, and verify ATEX, IECEx, FM, CSA, or EAC requirements.
- Select the measuring rod length according to the installation depth; if standard lengths are not applicable, select code 9 and define the TSP number.
- Select additional options according to medium corrosiveness; if perfluoro rubber is required, select code 2.
- Confirm tag requirements; if TAG identification is needed, select Z1 and provide the tag description.
- Summarize the complete model number, and check whether the special-type TSP number has been defined.
The final model number should be composed of each code segment in order, for example type + measuring rod length + additional options + certification + tag. For the specific arrangement, refer to the official model selection sample or technical manual.
Common Questions and Notes
- Special type: When code 9 appears, the TSP number must be defined; otherwise, the selection cannot be completed.
- Explosion-proof certification: G and K are not interchangeable and must be selected according to the target market and hazardous area.
- Non-hazardous area: C includes EAC marking, while 1 is for ordinary non-hazardous areas; their applicable areas differ.
- Measuring rod length: 120 mm, 225 mm, 360 mm, and 425 mm are standard options; select the special type if outside this range.
For more precise configuration, please confirm in combination with process connection, wetted materials, temperature and pressure range, and output signal.
