Product Details

The SBW series sanitary temperature transmitter and thermistor temperature transmitter are on-site installed temperature transmitter units in the DDZ-S series instruments. It adopts a two-wire transmission method (two wires as power input and a common transmission line for signal output). Transform thermocouple and thermistor signals into 4-20mA output signals that are linear with the input signal or temperature signal.

The transmitter can be installed in the junction box of thermocouples and thermal resistors to form an integrated structure. As a new generation of temperature measuring instrument, it can be widely used in industrial sectors such as metallurgy, petroleum, chemical, power, light industry, textile, food, national defense, and scientific research.

Adopting a silicone rubber sealing structure, it is shock resistant, moisture resistant, and suitable for installation and use in harsh on-site environments.

Installed on-site in the junction box of thermocouples and thermal resistors, it directly outputs 4-20mA, which not only saves expensive compensation wire costs, but also improves the anti-interference ability during long-distance signal transmission.

The transmitter has an open circuit indication function at the input end, and the thermocouple temperature transmitter has an automatic compensation function for cold end temperature.

High precision, low power consumption, wide temperature range for use, stable and reliable operation.

Widely applicable, it can form an integrated on-site installation structure with thermocouples and thermistors, and can also be installed as a functional module in detection equipment.

Intelligent temperature transmitters can use ZBT communication devices, a 386 or higher PC, to set the transmitter model, scale, and range of the measured temperature.

The digital temperature transmitter can adjust the display direction of the transmitter screen according to the actual needs of the user.

Main technical parameters of temperature transmitter

Input: Thermocouple K type, E type, B type, S type, T type, J type, N type

Thermal resistance Pt100Cu100Cu50 (three wire or four wire system)

Output: Output 4-20mA DC signal within the range of measurement. Linear with the millivolt signal input from the thermocouple; Linear with the input resistance signal of the thermistor. Or linearly with the temperature signal.

Isolation temperature transmitter, with input and output isolated, with an isolation voltage of 0.5KV to increase resistance to common mode interference, more suitable for computer networking use.

Basic error: * ± 0.5% FS

Transmission method: two-wire system

Display mode: (digital display type) LCD four digit display, displaying the E... symbol when the thermocouple is open circuit and outputting greater than 20mA.

Working power supply: The working power supply voltage of the transmitter ranges from a minimum of 12V to a maximum of 35V, with a rated working voltage of 24V.

Load: The maximum load resistance is calculated according to the following formula: RL (max)=50 (Vmin-12)

At 24V, the load resistance can be selected within the range of 0-600 Ω. The rated load is 250 Ω.

Normal working environment:

a) Environmental temperature -25 ℃~80 ℃ (normal temperature type) -20 ℃~70 ℃ (digital display type)

b) Relative humidity 5% to 95%

c) Mechanical vibration f ≤ 50Hz, amplitude<0.15mm

d) There is no medium in the surrounding air that corrodes chromium, nickel coatings, non-ferrous metals, and other alloys.

Environmental temperature impact: ≤ 0.05/1 ℃

Note: '. Users have special needs and can provide protocol products with an allowable error of ± 0.2%.
