Epson Toyo Communications has developed a "TSU" series of sensors that use the crystal oscillator to measure pressure with high precision. The frequency with a crystal oscillator varies with pressure, and the product uses this principle to measure pressure. The new product consists of four models, the maximum measuring pressure is from 100k to 1MPa, and the sample unit price is 400,000 yen.
The product is equipped with a dual tuning fork crystal oscillator with high stability and fast response. The characteristic is that the Q value (resonance sharpness) is high. By using this component, the product has high reproduction performance, excellent temperature characteristics, and low hysteresis loss. In addition, the frequency is generated by the built-in oscillating circuit, which reduces the influence from the length of the wire and makes it easier to assemble in the device.
Door panel: door panel is made of stainless steel 304 with no frame. Core materials are paper honeycomb, aluminum honeycomb, PU, EPS and etc. The installation sites of door lock, door closer and hinge are reinforced with square tubes of more than1.5mmthickness which are compression moulded by special technology.
Door frame: it is made of completely stainless steel 304. The connection types with wallboards are double-clip type and aluminum connection. The former is applied mostly to machine made wallboard and the latter hand made wallboard. The accessories are double window and lift type sweeping bar. The lock can be famous door lock or the owners can select lock brands themselves.
