L'errore analog-digital era sempre inferiore a 0,01 Brix. Il principale problema con analog input è che non c'è modo di rilevare quando il dispositivo Maselli smette di funzionare, perché l'ADAM continua a inviare l'ultimo valore.
|
||
Per risolvere in parte il problema, è stato modificato il valore di startup su ADAM a 1,5 mA, diverso dai 2 mA impostati da Masselli in errore. Questo funzionerà solo se ADAM viene riavviato rimuovendo i 24 V. Al riavvio, se non arrivano comunicazioni digitali da Masselli, ADAM fornirà 1,5 mA, indicando che il misuratore non è in funzione.

### UR62 vs UR29 — Key Specifications for Quality‑Control (QC)
|
||
|
||
| **Parameter** | **UR62 In‑line Refractometer** | **UR29 In‑line Refractometer** |
|
||
| --------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
|
||
| **Measuring range (Brix)** | 0 – 80 Brix | 0 – ==20 Brix== |
|
||
| **Maximum intrinsic error** | ± 0.20 Brix (stand‑alone); improves to ± 0.10 Brix when paired with repeater RC24/IR02 | ± 0.02 Brix within ±10 °C of calibration temp. |
|
||
| **Resolution** | 0.2 Brix (0.1 Brix with IR02) | – (not stated) |
|
||
| **Response time** | < 1 s | 1 s |
|
||
| **Product‑temperature window** | –25 … +90 °C (limited to +50 °C with built‑in cleaner) | –5 … +90 °C |
|
||
| **Process‑line pressure** | 10 bar @ 20 °C / 8 bar @ 90 °C | 10 bar @ 20 °C / 8 bar @ 100 °C (optional 15 bar version) |
|
||
| **Ingress protection** | IP67 | IP67 |
|
||
| **CIP / Sterilisation tolerance** | 95 °C water or 110 °C steam for 30 min | “See dedicated table” — manufacturer does not specify numeric limits in main data sheet |
|
||
| **Built‑in QC functions** | • Two alarm relays for concentration limits ± hysteresis• Third relay drives the automatic prism‑cleaning system • Integrated electrical prism cleaner • User OFFSET / SPAN calibration for zero & slope corrections | • RS‑485 interface to external analysis unit IB08; QC logic (alarms, logging) handled in the receiver, not in the sensor head |

#### What the numbers mean for quality control
|
||
|
||
- **Accuracy vs. range** – UR29 delivers an order‑of‑magnitude tighter accuracy (±0.02 Brix) but only up to 20 Brix; UR62 trades accuracy for a four‑times‑wider range, which may be acceptable if your QC limits allow ±0.20 Brix, or ±0.10 Brix when used with the IR02 repeater.
|
||
|
||
- **Process robustness** – Both units share IP67 protection and similar pressure limits; UR62 tolerates lower product temperatures (down to –25 °C) and includes documented CIP/SIP limits, which may simplify validation in food & beverage plants.
|
||
|
||
- **Automation** – UR62’s onboard relays, cleaning actuator, and user calibration make it a self‑contained QC device that can feed a PLC/SCADA directly. UR29 must be wired to an IB08 or MP‑series receiver for alarms, data logging, or cleaning logic, which adds an extra hardware layer but may suit legacy Maselli installations.

Use this table to match each meter to your concentration window and required QC precision:
|
||
_Choose UR29_ for low‑Brix, high‑precision syrup lines; _choose UR62_ where a single sensor must cover a broad 0–80 Brix span with built‑in cleaning and alarm handling.
