An AI sales agent's pressure transmitter order, checked before it goes out

An AI sales agent prepares an order for a WIKA model A-10 pressure transmitter: measuring range, output signal and supply, process and electrical connection, temperature range and approvals. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the combination limits in the public A-10 data sheet and returns a verdict, every reason and the figures it computed.

Scope: WIKA A-10 pressure transmitter orders: measuring range, output signal and supply voltage, non-linearity, process and electrical connection, temperature range, approvals, overpressure and loop load. See everything this validator covers

This validator models orders for the A-10 transmitter built from the public data sheet limits below, not just the scenarios shown.

  • Measuring range — gauge ranges from 50 mbar to 1,000 bar and absolute ranges from 100 mbar to 25 bar; the overpressure limit follows the data sheet bands (for example 2 times the range from 1.6 bar up to 600 bar) and the peak operating pressure is compared with it.
  • Output and supply — 4 to 20 mA, 0 to 10 V, 0 to 5 V, 1 to 5 V, 0.5 to 4.5 V and ratiometric outputs, each with its supply voltage range (standard up to 30 V DC or the 8 to 35 V option); the maximum load of the current output is (supply voltage minus 8 V) divided by 0.02 A.
  • Accuracy options — the improved 0.25 % non-linearity is not available at ranges of 0.1 bar or less, with the 0 to 5 V output or with the 8 to 35 V supply; the 0 to 5 V output is not offered at 0.1 bar or less.
  • Connections — G 1/8 B and 1/8 NPT are limited to 400 bar, the flange connection to 100 bar, and the SAE connection to -20 degrees C and above; the angular DIN connectors are IP65 while the M12 connector and cable outlet are IP67.
  • Temperature and approvals — the -40 to +100 degrees C range needs the 4 to 20 mA output and a housed site protected from condensation, and is not combined with the DNV or cULus approvals; the 8 to 35 V supply is limited to 80 degrees C.

Any A-10 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none were used, so this validator produces no price build-up or line-item quote), other WIKA models, the full list of standard ranges and units, seal materials, pressure port and T-restrictor options, the overpressure of ranges above 600 bar, and limits where the two data-sheet copies read differed (for example UL and DNV range limits). Supply voltages are entered in whole volts.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A pressure range that decides which connections, options and outputs are allowedOnly with care
The 0.1 bar, 100 bar, 400 bar and 600 bar boundaries each need their own rule, and each is easy to miss when a range is picked from a list.		The range is one number in the request and every boundary is checked on every call.
An output signal whose supply voltage range depends on the output and the supply optionOnly with care
The allowed voltages belong to the output and supply choices, so a lookup table and a separate validation rule are needed.		The output, supply option and voltage are compared together on every call.
A maximum load that follows from the supply voltage, and an overpressure limit that follows from the rangeOnly with workarounds
These are formulas rather than choices, so they need calculated fields and a rule that compares them with what the agent stated.		Both figures are computed from the order and compared with the agent's stated figures.
A temperature range that restricts the output, the site and the approvalsOnly with workarounds
One option constrains several others, so each pairing needs a rule and the set grows with every option.		The temperature range is checked against output, site, supply and approvals in one pass.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a WIKA model A-10 pressure transmitter: measuring range, output signal and supply, process and electrical connection, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the combination limits in the public A-10 data sheet and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 20 WIKA A-10 pressure transmitters with a gauge range of 0 to 16 bar, a 1 to 5 V output powered at 24 V DC. The quote states an overpressure limit of 32 bar. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The -40 to +100 degrees C range is offered with the 4 to 20 mA current output only. The -40 to +100 degrees C range is only possible when the installation site is housed and protected from condensation. The DNV and cULus approvals are not available with the -40 to +100 degrees C medium temperature range.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a temperature range that restricts the output, the site and the approvals, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the output signal to 4 to 20 mA, the site protected from condensation to yes and the DNV approval to no. It sets the loop load to 600 ohm and the stated maximum load as to 800 ohm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
