この発明は通常データロガーと呼ばれる多数点の測定
データを集収し印字記録を行うデータ集録装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data acquisition device commonly called a data logger that collects measurement data from multiple points and records the data in print.
従来、この種の小型のデータ集録装置の入力端子部は
、ただ単にケースの上面又は後部に入力端子を多数設け
、これに熱電対線等を接続するようにしていた。Conventionally, the input terminal section of this type of small-sized data acquisition device has simply been provided with a large number of input terminals on the top or rear surface of the case, to which thermocouple wires or the like are connected.
しかしながら、このような方法では、例えばデータ集録

装置を提供することである。However, in such a method, for example, when a data acquisition device is installed on a panel or the like, wiring is extremely difficult and requires a great deal of labor. Additionally, if the data acquisition device itself and the measurement location are far apart, long thermocouple wires, etc. must be run from the measurement location to the input terminal built into the data acquisition device, which increases wiring costs. This would have been practically impossible. Furthermore, when there is a heat source in the vicinity of the data acquisition device, the temperature distribution at the input terminal section inevitably becomes non-uniform, causing measurement errors unless it is heated uniformly, making it difficult to measure with high accuracy. The purpose of the present invention has been made in view of the above-mentioned points.The purpose of this invention is to make the input terminal box detachable from the main body of the data acquisition device, thereby making wiring very easy. An object of the present invention is to provide a data acquisition device that can be installed and used separately.
以下、図面に従つて、この発明を説明する。 The present invention will be described below with reference to the drawings.

A second roll 11 is provided at the lower part of one front end of the rail 10, and an L-shaped protrusion 12 is also provided at the upper part of the front end. Further, a rocker 13 is rotatably attached to a support shaft 14 on the front side surface of the input terminal box 1, and one end of the rocker 13 is formed into a recess 15, which protrudes from the inner side surface of the data acquisition device main body 2. It is adapted to engage pin 16. Further, an intermediate stopper 17 is rotatably attached to a support shaft 18 on the rear side surface of the input terminal box 1, and one end thereof is an L-shaped portion 19.
When it is pulled out from the data acquisition device main body 2, it engages with the protrusion 12 of the second rail 10. The description of this invention configured as above will be further continued.

9 and the protrusion 12 are released, and the projection 12 is disengaged. The power terminal box 1 can be completely pulled out from the data acquisition device body 2 as shown in FIG. In this state, wiring can be done extremely easily and quickly. After wiring is completed, the first roll 9 of the input terminal box 1 is brought into contact with the inside of the second rail 10, just as when the input terminal box 1 is pulled out, and the first rail 8 is connected to the second rail 10. The input terminal box 1 can be attached to the data acquisition device main body 2 very easily by contacting with the roll 11 of the input terminal box 1.

場合にも測定可能としたデータ集録装置である。In addition, if the data acquisition device main body 2 and the measurement location are far apart, as shown in FIG. The input terminal box 1 is installed at this remote location, and after receiving the measurement input signal, it is transmitted to the data acquisition device main body 2 through the dedicated cable 20, and data can be collected centrally. The conductor wire can be short. Furthermore, if extremely high-precision measurement is desired, only the input terminal box 1 can be placed in a thermostatic oven and the measurement can be carried out while maintaining complete temperature uniformity. As described above in detail, the present invention is a data acquisition device in which the input terminal box is detachably attached to the data acquisition device main body, and measurement is possible either when it is attached or when it is installed separately.

大である。Therefore, since the input terminal box is removable from the main body of the data acquisition device, wiring can be performed extremely easily. Furthermore, if an input terminal box is prepared in advance to which the required type of thermocouple is wired, the type of input can be changed extremely quickly by replacing the input terminal box. In addition, since the input terminal box can be installed separately, when making measurements at a remote location, you can connect the data acquisition device and the input terminal box with a dedicated cable made of conductor made of ordinary Cu, etc. There is no need to draw pairs or compensation conductors, and wiring man-hours and costs can be significantly reduced. In addition, since the input terminal box is placed in a constant temperature bath, the temperature can be more uniformly heated, which has extremely great practical effects such as extremely high precision measurement.
