Abstract
The utility model provides an exhaust temperature meter compensation adjusting resistor box. The exhaust temperature meter compensation adjusting resistor box comprises a circuit board, wherein the circuit board is provided with at least one adjustable resistor as well as an exhaust temperature meter interface, a thermocouple interface and a temperature sensor interface which are corresponding to the adjustable resistor one by one, the upper end of each adjustable resistor is connected to the exhaust temperature meter interface, and the lower end of each adjustable resistor is respectively connected with the thermocouple interface and the temperature sensor interface. By adopting the exhaust temperature meter compensation adjusting resistor box, the cost is reduced, and the convenience in repairing is realized.
Description
Technical field
The utility model relates to a kind of row's temperature table compensation adjustment resistance box.
Background technology
In most naval vessels, the thermocouple compensating resistance of main frame row temperature table is the fixed resistance of wire-wound, and is connected with outside line by two ends binding post.Due to cabin operational environment relatively severe (temperature is high, high humidity), binding post and fixed resistance brace are very easily oxidized, often because of loose contact, cause the index error of row's temperature table, cannot correctly indicate row's temperature of each cylinder, normal operation to main frame causes potential safety hazard, and aspect M R, very inconvenience, not only will take much time, and also needs many people to coordinate just and can complete adjustment work.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of row's temperature table compensation adjustment resistance box, has reduced cost and has been convenient to maintenance.
The utility model is achieved in that a kind of row's temperature table compensation adjustment resistance box, comprise a circuit board, described circuit board is provided with at least one adjustable resistance, and arrange one to one temperature table interface, thermocouple interface and temperature sensor interface with described adjustable resistance, the upper end of described adjustable resistance is connected to described row's temperature table interface, and the lower end of described adjustable resistance connects respectively described thermocouple interface and described temperature sensor interface.
Further, described circuit board also comprises and described adjustable resistance spare interface one to one, and described spare interface is connected to the lower end of described adjustable resistance.
Further, described adjustable resistance is 3296 types, the accurate wire-wound multi-turn adjustable resistance that resistance is 10 ohm.
Further, also comprise containment vessel, the upper and lower two ends of described containment vessel are respectively equipped with a hole, and described circuit board is fixed on described containment vessel.
The utility model has the advantage of: use the utility model row temperature table compensation adjustment resistance box to improve the pointing accuracy of row's temperature table, make system works stable, reliable, adjustment is convenient, and simultaneously not affected by environment, precision is high, and cost is lower, and is convenient to maintenance.
Accompanying drawing explanation
The utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is the utility model structural representation.
