IPC704 ordering code
Base part number 244-704-000-XXX followed by codes A to G:
Replacement options
“Without” for a form, fit and functionally identical replacement. “With” for SIL 2 applications.
“-1 dB” keeps the same IPC704 cutoff frequency. “-3 dB” applies the ISO 2954 standard filtering.
“Custom” for the exact same IPC704 transfer. “Standard” for the closest new standard transfer.
The result updates as you type. Code C and D units follow the selected B type automatically. The conversion reproduces the official IPC704 to IPC707 ordering code conversion table, revision 05.

The orange marker indicates the ordered IPC707 operating point (code C of the resulting PNR) on the standard sensitivity curves and updates automatically as you change inputs or snap to a standard transfer.
03 · Reference
Conversion rules & limits
The IPC707 replaces the IPC704 with the fixed base part number 244-707-000-012. Codes A, E and F carry over from the IPC704 (E and F are rounded to the IPC707 coding format, and F is scaled when the -1 dB option is chosen). Codes B, C, D and G are translated as described below.
Code translation
| A · Environment | Carried over unchanged: 1 = standard (non-Ex), 2 = Ex ia (intrinsic safety), 3 = Ex ec / nA (Zone 2). |
|---|---|
| B · Diagnostics | From the Diagnostic option: Without = B1, With (SIL 2) = B2. |
| C · Transfer sensitivity | Computed from the IPC704 sensor and output sensitivities: transfer = output sensitivity ÷ (sensor sensitivity ÷ k), where k converts the measurand to the per-pC transfer domain. Rounded to 4 significant digits, maximum 2 decimals. |
| D · Transfer units | From the IPC704 B type: 1 = µA/pC, 2 = mV/pC, 3 = µA/pCs, 4 = mV/pCs. |
| E · High-pass filter | Carried over, rounded to 3 significant digits, maximum 1 decimal. |
| F · Low-pass filter | Carried over, rounded to 3 significant digits. With the -1 dB option the cutoff is multiplied by 1.24 so the -1 dB point of the IPC707 matches the IPC704 cutoff. |
| G · Mounting | IPC704 G0 = IPC707 G1 (two M4 screws, without DIN-rail adaptor); any other value = G2 (with MA130 DIN-rail adaptor). |
Transfer domain factor k
| Acceleration types (B1, B2) | k = 1 — transfer in µA/pC or mV/pC |
|---|---|
| Velocity, metric (B3, B4) | k = 9810 — transfer in µA/pCs or mV/pCs |
| Velocity, imperial (B5, B6) | k = 9810 ÷ 25.4 ≈ 386.22 — transfer in µA/pCs or mV/pCs |
| Pressure, bar (B7, B8) | k = 1000 — transfer in µA/pC or mV/pC |
| Pressure, psi (B9, B10) | k = 1 — transfer in µA/pC or mV/pC |
Standard transfer sensitivities
With the Standard option, the computed transfer is replaced by the closest standard value not exceeding it:
Per-pC transfers (µA/pC, mV/pC)
| Values | 0.1 · 0.2 · 0.5 · 1 · 2 · 5 · 10 · 20 · 50 |
|---|
Per-pCs transfers (µA/pCs, mV/pCs)
| Values | 981 · 1962 · 4905 · 7553.7 · 9810 · 19620 · 49050 · 98100 |
|---|
IPC707 ordering limits
The converted code is checked against the valid IPC707 ordering ranges. Outside these limits the ordering code is not possible:
| A · Environment | 1 to 3 |
|---|---|
| B · Diagnostics | 1 to 2 |
| C · Transfer sensitivity | 0.1 to 110 (µA/pC, mV/pC) · 981 to 98100 (µA/pCs, mV/pCs) |
| D · Transfer units | 1 to 4 |
| E · High-pass filter | 0.5 Hz (without diagnostics) or 1 Hz (with diagnostics) to 110 Hz |
| F · Low-pass filter | 200 Hz to 20 000 Hz. The current IPC707 additionally offers a 50 kHz standard low-pass cutoff (since DS 262-713 v13, without diagnostics B1 and without integrator D1/D2 only); the IPC704 never offered 50 kHz, so it cannot result from a conversion. To order it, use the IPC707 configurator. |
| G · Mounting | 1 to 2 |
