Industrial 4-20ma PT1000 Temperature Sensor PT100 Temperature Transmitter For Oil

NCS-TT105 smart temperature transmitter adopts fieldbus technology, is a new generation of fieldbus smart temperature transmitter, and is an indispensable field device in process control. The device integrates rich functional modules, which can realize both general detection functions and complex control strategies.

NCS-TT105 adopts digital technology, which can be applied to a variety of thermal resistance and thermocouple sensors, with a wide range, simple interface between the field and the control room, and can greatly reduce the cost of installation, operation and maintenance.

NCS-TT105 smart temperature transmitter supports HART, FF, PA protocol and can be widely used in petroleum, chemical, power plant, metallurgy and other industries.

NCS-TT105

Multiple protocols:

FF H1, PROFIBUS PA, and HART protocol with the latest version， DD files are available.

High accuracy ± 0.05% at full scale

Using a high-precision A/D acquisition chip to collect and detect signals, the conversion result is closer to the actual signal.

Backup function

Dual channels can back up each other redundantly, self-diagnose sensor faults, and measure temperature with correct sensors.

Ex ia and Ex d product

Safer; It can prevent damage and can be applied in explosion-proof sites. The product hardware schematic diagram and PCB are designed according to intrinsic safety and approved by the organization.

LCD Display

The LCD display is more transparent, and the field instrument inspector can know the instrument status and process acquisition variables by viewing the LCD display.

Low-temperature drift, less than 50ppm/℃

Low-temperature drift device is adopted to minimize the influence of ambient temperature on the acquisition accuracy of the equipment.

External Pt100 can be used for cold-end measurement

It is realized by connecting terminals, and the software configuration type is PT100, which can measure the temperature value corresponding to the PT100 sensor.

The cold end compensation function of the thermocouple requires that the temperature of the reference of the thermocouple should be constant, generally at 0 ℃ according to the temperature measurement principle of the thermocouple.

Therefore, we need to develop a cold-end compensation algorithm to ensure the temperature collected by the thermocouple is accurate.

Flexible configuration: supporting multiple thermal resistance thermocouple sensors, supporting 2-wire, 3-wire, and 4-wire wiring modes, and thermocouple cold end compensation function.More choices for users: There are many types of sensors supported by the instrument so that users can use them more flexibly.

White backlight

The display is more transparent.

Our PC software and DD files are available.

It can be easily configured to realize the fast configuration of the instrument.

Support two channels, 4 types of thermal resistance, and 8 types of thermocouples.

Thermal resistance supports 2-wire and 3-wire wiring modes.

The compensation accuracy of the thermocouple cold end can reach ± 1.0 ℃.

For installing a smart temperature transmitter, there are three types of mounting brackets available: tube-mounted flat bracket, tube-mounted curved bracket, and disk-mounted curved bracket. Correspondingly, there are three installation methods, namely flat bracket tube installation, curved bracket plate installation, and curved bracket tube installation. The installation methods are described below:

A typical installation of flat bracket tube installation is shown in the picture,fix the transmitter on the tube-mounted flat bracket, and then fix the tube-mounted flat bracket to the vertical tube of about Φ50mm through U-bolts.

The picture shows the typical installation method of the curved bracket plate installation. Fix the transmitter on the panel mounting bracket, then fix the panel mounting bracket on the dial with M10 bolts (provided by the user).

Pictures show the typical installation method of the curved bracket tube installation. Fix the transmitter on the tube mount bracket, then fix the tube mount bracket to the horizontal pipe of about Φ50mm through U-bolts.

FF transmitter supports many kinds of connection, as shown in picture.There is a transmitter bus connection; the bus ends are connect terminal matching resistance, which ensures the signal quality, as shown in picture. The maximum length of bus is 1900 meters and it can be prolonged to 10 kilometers with repeaters.

The connection mode of the temperature transmitter includes (4~20) mA compatible mode and networking mode.

A PROFIBUS PA network topology can have a variety of different structures, as shown in picture. It shows the bus connection of the PA instrument. Both ends of the bus need to be connected to terminating resistors to ensure the quality of the bus signal. The bus has a maximum length of 1,900 m and can be extended to 10 km using a repeater.
