步骤：1、在使用前，先用手将付针(红针)回零，然后再进行压力测试，其中主针(黑针)显示当前压力，付针显示测试过程中最大压力。 Steps for using a shock-resistant bimetal thermometer : 1. Before use, return the auxiliary needle (red needle) to zero by hand, and then perform the pressure test. The main needle (black needle) displays the current pressure, and the auxiliary needle displays the test process. Medium maximum pressure. 2. After use, return the needle to zero. 3. Do not open the pressure gauge after it fails to avoid damage. 4. The verification procedures carried out by this pressure gauge are JJG52-87. 5. When two or more pressure gauges are used for one device, a boxed double-needle shockproof pressure gauge can be selected. The shock-resistant electric contact bimetal thermometer is a kind of on-site measuring instrument for measuring low and medium temperature. It can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ～ + 500 ℃ in various production processes. This shock-resistant electrical contact bimetal thermometer is filled with shock-resistant oil from the inside of the instrument, which can effectively overcome the pointer shake caused by mechanical vibration. The design principle and structure are waterproof, corrosion-resistant, shock-resistant, intuitive, easy to read, mercury-free, durable Features.
是一种测量中低温度并且生产现场对温度需自动控制和报警的检测仪表。 The shock-resistant electric contact bimetal thermometer is a measuring instrument that measures low and medium temperatures and requires automatic control and alarming of temperature at the production site. The shock-resistant electrical contact bimetal thermometer can directly measure the harsh and vibrating temperature of liquid, steam and gas medium in the range of -80 ℃ ～ + 500 ℃ in various production processes. The thermometer is waterproof, corrosion-resistant, vibration-resistant, intuitive, easy to read, mercury-free, rugged and durable from the design principle and structure. It is widely used in petroleum, chemical, machinery, marine, power generation, textile, printing and dyeing industries and Scientific research department. Main features: On-site temperature display, intuitive and convenient; safe and reliable, long service life; multiple structural forms can meet different requirements. Mercury-free, easy to read, rugged and shock-resistant. The protective tube is 1Gr18Ni9Ti stainless steel and titanium molybdenum, which has strong pressure and corrosion resistance. Pull-type thermometer can be maintained or replaced for a short time without stopping the machine. The integrated types include axial, radial, and universal types, which are suitable for various site installation needs.
是基于绕制成环性弯曲状的双金属片组成。 The shock-resistant electric contact bimetal thermometer is based on a bimetal sheet that is wound into a loop shape. When one end is heated and expanded, the pointer is driven to rotate, and the working instrument displays the corresponding temperature value, and prevents environmental vibration. The bimetal thermometer is filled with silicone oil or the display part of the bimetal thermometer is separated from the measurement part to achieve the effect of shock resistance. The electric contact bimetal thermometer uses the change of temperature to drive the change of the contact. When it is disconnected with the upper or lower limit contact, the relay in the circuit is activated, so as to automatically control and alarm. Executive standard: JB / T8803-1998 GB3836-83, other parameters Nominal diameter of the dial: 60 100 150 Accuracy class: (1.0), 1.5 Thermal response time: ≤ 40S Protection level: IP55 Angle adjustment error: Angle adjustment error should not 1.0% hysteresis exceeding its range: Hysteresis electrical contact bimetal thermometer hysteresis should not be greater than the absolute value of the basic error limit Repeatability: Shockproof electrical contact bimetal thermometer repeatability limit range should not be greater than 1 / the absolute value of the basic error limit 2
