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)

Device structure RTD average temperature signal for local HART conversion

Measuring range • Temperature measurement

• 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,

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

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.

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.
