Description
Electric contact bimetal thermometers are used in production sites to automatically control and alarm the temperature. Electric contact bimetal thermometer can directly measure the temperature of liquid, steam and gas medium in the range of -80-500℃ in various production processes.
Features:
O On-site temperature display, intuitive and convenient;
O With automatic power off and alarm function;
O Safe and reliable, long service life;
O A variety of structural forms to meet different requirements.
working principle:
The electric contact bimetal thermometer uses the temperature change to drive the contact change. When it contacts or disconnects with the upper and lower limit contacts, the relay in the circuit works, so as to automatically control and alarm.
The main technical parameters:
O Product implementation standard: JB / T 8803-1998; GB 3836-2000
O Dial Nominal Diameter: Ф100
O Accuracy class: (1.0), 1.5
O Thermal response time: ≤40S
O enough protection level: IP55
O Normal working atmospheric conditions: temperature - 25-+55 ℃, relative humidity ≤ 85%
O Set point error: The set point error should not exceed 1.5 times the basic error limit
O Switching difference: The switching difference should not exceed 1.5 times the basic error limit
O Switching repeatability: The switching repeatability limit range is not greater than 1/2 of the absolute value of the basic error limit
