Standard signal generator

An input circuit includes a rectifier circuit that rectifies an excitation current obtained from a converter, and a constant voltage circuit that receives output of the rectifier circuit and performs control so that a power supply voltage is maintained constant. A power supply voltage source switching unit switches the source of a power supply voltage used in a calibrator to the constant voltage circuit when the converter is a converter of a four-wire electromagnetic flowmeter, and switches the source of the power supply voltage to a battery when the converter is a converter of a two-wire electromagnetic flowmeter. ...

Photoelectric sensor

A photoelectric sensor includes a current division control circuit that sequentially sets a reference voltage for each current divider circuit along one of the arrangement directions of photodiodes so that the reference voltage for the current divider circuit is equal to or larger than the voltage value of the reference voltage set for a current divider circuit in the preceding stage, and sets one common control voltage for all of the current divider circuits, the common control voltage falling within a range that includes all of the reference voltages.. . ...

Positioner

A positioner includes: a displacement amount detector that outputs a pair of detection signals; a multi-layered board that propagates a pair of detection signals; a circuit board on which an electronic circuit generating a control signal for controlling a valve opening of the regulating valve, on the basis of the pair of detection signals is formed; and a housing that accommodates at least the multi-layered board and the circuit board. The multi-layered board includes a first interconnection layer having a first interconnection pattern formed therein, and a second interconnection layer that has a pair of signal interconnections formed therein and is disposed on the first interconnection layer through an interlayer insulation film. ...

Positioner

A positioner includes: a displacement amount detector that outputs a pair of detection signals; an interconnection board that includes an interconnection layer which is disposed between two insulating layers and has a pair of signal interconnections, having the pair of detection signals supplied thereto, formed therein; a circuit board on which an electronic circuit generating a control signal for controlling a valve opening of the regulating valve on the basis of the pair of detection signals is formed; and a housing. The interconnection board is bonded to the housing by a conductive adhesive member in at least a portion of a surface of any one of the insulating layers, and the adhesive member has a measured value of hardness, which is obtained by a type d durometer after hardening, being in a range of equal to or greater than d20 and equal to or less than d90.. ...

Regulating valve

To provide a regulating valve whose stability of an operation is high,a regulating valve is disclosed that includes a valve box in which a first flow channel and a second flow channel are formed, a cage having a first throttle portion provided in a boundary between the first flow channel and the second flow channel, a plug head having a second throttle portion slidably inserted into an inside of the cage, and a guide ring slidably holding a plug guide holding the plug head. In a closed state of the regulating valve, a distance between a through-hole of the first throttle portion and an end portion of the plug head on the other end side is shorter than a distance between a through-hole of the second throttle portion and an end portion of the cage on the opened one end side.. ...
