黄岩县院桥轻工机械厂针对在低温环境中影响照片显影质量的问题,特研制成功K S H—3 B型可控硅盘式恒温控制箱。该箱采用不锈钢封装热敏元件置于显影、定影液中连续检测温度,温度信号经差动放大电路,控制可控硅的开通角,从而达到自动控制温度的目的。可用于低温环境中X光片、黑白和彩色胶片、胶卷的冲洗,广泛应用于无损探
Huangyan County Hospital Bridge Light Machinery Factory in low temperature environment for the impact of the quality of photo development, especially developed K S H-3 B-type silicon controlled thermostat tray. The box with stainless steel thermal components placed in the developer, the fixing solution for continuous detection of temperature, the temperature signal through the differential amplifier circuit to control the SCR opening angle, so as to achieve the purpose of automatic temperature control. Can be used in low temperature X-ray film, black and white and color film, film processing, widely used in nondestructive exploration
