Transcription

1 Technical Information Prothermo NMT 532 Intrinsically safe multi-signal converter with precision average temperature sensor for inventory control Application The Prothermo NMT 532 consists of an intelligent HART signal converter and average temperature sensor. For average temperature measurement, it consists of precision multi-spot Pt100 (Max.6) elements which have fixed interval (2 m or 3 m). The NMT 532 is a highly capable solution for a variety of tank gauging applications and provides constant average temperature data via HART communication. For accurate inventory measurement, it is best suited connected to Tank Side Monitor NRF 590 with Micropilot radar tank gauge or NMS53x series Proservo. Features and benefits High accuracy Intrinsically safe device allowing for the safest electrical configuration possible. Compatible with user friendly ToF (Time-of-Flight) tool Simple and Economical Compact size and weight High-reliability and easy installation Maintenance free TI 049N/08/en/05.06 Software Ver. 1.45

3 Function and system design Measuring System The NMT 532 is compact and economical. The average Temperature sensor consists of six Pt100 elements at 2 or 3 meter intervals. Temperature data is transmitted to the Tank Side Monitor NRF 590 or NMS53x via intrinsically safe 2-wire HART signal.

Basic functionality of the NMT 532 is displayed and configured on the NRF 590. Detailed NMT 532 functionality and data access can be performed by the ToF tool. The NMT 532 receives radar level data from the NRF 590 and then calculates liquid and gas phase average temperature. Calculated and standard data, including temperature element raw data and device status, are transmitted to the NRF 590. Depending on the size of the tank farm and data processing functionality, measurement data can be transmitted to various interface units via V1 protocol or other industry standard communication protocols (please see the NRF 590 technical information). All gathered data in the interface unit is sent to inventory management software, such as FuelsManager or NXS-310 (MDP-II program), or directly sent to the customer's specific DCS or PLC. 4 Endress+Hauser

All the necessary configuration and parameter settings for the NMT 532 are performed via either the Proservo NMS 53x or ToF tool. The NMT 532 receives liquid level data from the Proservo, then calculates liquid and gas phase average temperature. Calculated data and basic information, including raw data for each temperature element and device status, are transmitted to the Proservo. From the Proservo NMS 53x, all sensor data are sent to the interface unit via V1 communication protocol. Since the Proservo is a multi-functional device (measurement and data transmission), a Promonitor NRF 560 can act as a tank side remote data indicator and controller for Proservo. The standard NRF 560 has no data transmission functionality. All gathered data in the interface unit is sent to inventory management software, such as FuelsManager or NXS-310 (MDP-II program), or directly sent to the customer's specific DCS or PLC.
