3 Product description
3.1 Product design
NMT539 performs precise liquid and gas phase average temperature measurement, which
makes it ideal for inventory management of large-scale tanks.
It is equipped with a capacitance WB device in crude oil and two-phase liquids, and it
performs accurate average temperature and WB measurements.
The position of the flange cannot be adjusted in a welding flange type.
3.2 Technical data
Item Details
Application • Flange installation: Standard 50.8 mm (2 in)
• Temperature measuring range: Maximum length 99.999 m (3.94 in) (ATEX, IECEx, NEPSI, FM C/US), maximum length
40.000 m (1.57 in) (TIIS)
• WB measuring range: 1 m (3.28 ft) or 2 m (6.56 ft)
Measuring principle • Temperature measurement
NMT539 consists of up to 16 platinum resistance elements (Pt100) in a SUS316 protection tube. Pt100 has a unique
characteristic of linear resistance change with respect to the surrounding ambient temperature change. A module in the
NMT539 converter receives this resistance signal change as an input variable and converts it to temperature data. The
converted and calculated data are then transmitted to the host device as a local HART signal.
• Water bottom (water interface level) measurement
An attached capacitance level measurement probe detects the presence of water.The WB is converted into a given frequency
variable (default setting) and its data is transmitted via local HART converter to the connected host device.
Minimum element
interval (distance)
• Standard specifications: 150 mm (5.9 in) (Order Code: 030 Option 1, 4, 5)
• High temperature / Low temperature: 400 mm (15.75 in) (Order Code: 030 Option 2, 3, 6)
If NMT539 comes with a WB (water bottom) probe option, the maximum number of WB internal elements is two,
because of the restriction posed by the internal diameter.

Typical application of NMT539 converter + temperature probe version
NMT539 is the successor of the former NMT535. For proper migration, NMT539 has
inherited all the functionality and specifications of NMT535, including connection flange
specifications, cable entries and wiring method. Since NMS5 or NMS8x is provided with
WB measurement function, they can be combined with the converter + average
temperature probe version of NMT539. When the converter + average temperature probe
+ WB probe version is combined with NMS5 or NMS8, the product in the tank will
simultaneously be managed with level, continuous temperature and WB measurements.
Most changes and parameter settings for NMT539 can be performed by NMS5 or NMS8x.
NMT539 receives liquid level data from NMS5 or NMS8x and then calculates the average
temperature of the liquid and gas phases. The calculated average temperature data of the

Product description Prothermo NMT539

liquid and gas phases are transmitted to NMS8x or NMS5 along with the measured
temperature of each element and the NMT539 device status.
All gathered data in the field interface unit are sent to inventory management
software (Tankvision) or to NMS8x, NMS5x, NMS7, NMR8x, NRF8x or NRF590.

3.3.3 NMT539 Ex ia and NRF590 Ex d [ia] combination
Typical application of NMT539 converter + temperature probe + WB probe version
The NMT539 converter + temperature probe + WB probe version is utilized most
effectively in combination with radar level gauging. Water interface, temperature and
liquid level measurement, with data collection and calculations via the NRF590 or NRF81,
allow for optimal inventory control.Details on NMT539 functions and data can be accessed
from NRF81 or NRF590. NMT539 receives radar level data from NRF590 or NRF81 and
then calculates the average temperature of the liquid and gas phases. The calculated
average temperature data of the liquid and gas phases are transmitted to NRF81 or
NRF590 along with the measured temperature of each element and the NMT539 device
status.
All gathered data in the field interface unit are sent to inventory management
software (Tankvision) or to NMS8x, NMS5x, NMS7, NMR8x, NRF8x or NRF590.

3.3.4 NMT539 Ex d [ia] and TMD1 Ex d combination
Average temperature device NMT539 can be connected to Transmitter TMD1 or Servo
Level Gauge TGM5 via local HART (Ex d) communication. Because local HART
communication is digital, it is able to send a larger volume of information compared to the
conventional RTD method. This means that NMT539 can work with not just DRM9700 but
also with NRF560. If NMT539 WB probe and NRF560 are used together, confirm that the
supply voltage to TMD1 is stable at 100 VAC or higher.
