Tank gauging role
The Prothermo NMT81 family is designed for precise average temperature measurement in tanks and can integrate with systems such as Proservo NMS80-series devices, Micropilot NMR81/NMR84 and TankSideMonitor NRF81. Up to 24 RTD elements and redundant sensor processing are available at family level, depending on configuration.
Published family references
- Average-temperature accuracy reference: ±0.032 °C with five-point calibration.
- Maximum immersion length on request: up to 100 m.
- Multiple temperature-range options, including cryogenic and elevated-temperature versions.
- Optional continuous water-bottom measurement using a capacitance sensor.
- Corrosion-resistant process parts and hazardous-area approvals are available by configuration.
These are NMT81 family capabilities. The exact sensor length, number of elements, spacing, process connection, approval and water-bottom option for Endress+Hauser NMT81-154U90 Prothermo average temperature probe must be confirmed from the order code and nameplate.
Information needed for replacement
Provide tank height, installation nozzle, required immersion length, element arrangement, process temperature, hazardous-area classification, connected tank-gauging equipment and current nameplate photographs. For custody-transfer work, also state the required metrology and calibration documentation.
Buyer note
Keeping NMT81-154U90 together with NMT81-BBTAAMFEB0ABA1B1NB00EBEQJ00 in the RFQ helps prevent a probe with the wrong length or sensor arrangement from being selected.
