Specifications and models of RLC thermostats

1. The installation of the level gauge must be vertical to ensure that the inner pontoon can move up and down freely in the pipe body. 2. Install a shut-off valve between the container and the liquid level gauge to clean and overhaul the liquid level timing to cut off the material. 3. No magnets are allowed to approach around the main body of the pontoon level gauge, otherwise ...

1. Turn on the power of the smart thermostat, and the current temperature is displayed on the display. Because the sensor is not in contact with other devices, but is exposed directly to the air, this is the current temperature: 31 degrees Celsius, which is not too hot. 2. At the bottom right of the display is the "Startup Temperature" setting.

In a variety of electronic control equipment, digital display has become an indispensable and important link. The electronic devices and corresponding driving circuits used for digital display are called digital displays. Commonly used digital displays include glow digital tube displays, fluorescent digital tube displays, projection ...

1. After heating for a period of time, it is found that the temperature has not changed, and the temperature has been displayed at the time of the ambient temperature. In this case, you need to check that the SV value setting value is set, whether the OUT value indicator of the meter is not lit, and whether the No. 3 and 4 segments of the universal meter are 12VD ...

1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET button at the beginning of the digital tube character flashing, indicating that the appearance has entered the setting state, press the △ key to add the set value, press the v key to decrease the setting value, press and hold the △ key or √ key The data will change rapidly, press the SET key again ...

1. The principle of central air conditioning thermostat Mechanical thermostats can be divided into vapor pressure thermostats, liquid expansion thermostats, gas adsorption thermostats and metal expansion thermostats. Among them, the vapor pressure thermostat is divided into inflatable type, liquid-gas mixed type and liquid-filled type. Domestic...

The rkc controller was developed by Japan and is mainly used in plastics and stoves. Of course, it is also widely used in China's industry, there are many people who do not know much about the rkc controller, and some even feel unfamiliar.

(1) RH400 size: 48*96, depth 60, about 250g Details: ●A variety of input types are available: 1) Thermocouples: K, J, R, S, B, E, N, T, W5RE/W6RE, PL‖, U, L 2) Temperature measurement RTD input: PT100, JPT100...

1. Power conversion: convert the voltage (rated 100V) and current (rated 5A or 1A) of the transformer into voltage (several volts) to meet the requirements of weak current components. 2. Isolation: current, secondary side security, and work grounding are used to ensure the safety of people and equipment, while weak current ...

1. Set temperature: press and hold the SET key, at this time the tube character begins to flash, proving that the instrument has entered the set state, increase the up button, decrease the down button, and press and hold the up and down buttons to quickly change, when the desired temperature is reached, then press the SET button The instrument is set. 2. Return control: press SET ...

1. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

　　A relay is an electrical appliance that works automatically. When the amount of electricity such as voltage, current, and frequency or non-electricity such as temperature, pressure, and rotational speed is input to the relay, and when the specified value is reached, the contacts of the relay connect or cut off the circuit that controls or protects it. Relays are widely used in motor control and power ...

(1) Categorize by display color 1. Monochrome display There are two types of displays: multi-grayscale monochrome display and VGA multi-frequency monochrome display. These displays are small, lightweight, clear and inexpensive, making them suitable for highly mobile workplaces. 2. Color ...

In temperature measurement, thermocouples and RTDs are both contact temperature measurements, and although they both measure the temperature of an object, their principles and characteristics are different. This article first introduces thermocouples, which are widely used in temperature measurement temperature control devices.

The normal operation of the instrument is inseparable from the on-site maintenance relationship, especially some important process links, once there is a leak, it will greatly affect the quality of the product, resulting in heavy losses. First of all, it is common to install both remote and field-indicated level gauges on important tanks.

* Alarm table {ALM1} (standard built-in) A: Upper limit deviation alarm G: Standby upper and lower limit deviation alarm attached B: Lower limit deviation alarm H: Upper limit input value alarm C: Upper and lower limit deviation alarm J: Lower limit input value alarm D: Alarm in the range K: Attached standby ...

1. The temperature controller control method is generally divided into two types: One is controlled by the temperature change of the cooled object, and the vapor pressure temperature controller is mostly used, and the other is controlled by the temperature difference change of the cooled object, and the electronic temperature controller is mostly used. ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube characters to start flashing, indicating that the instrument has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again ...

1. For thermocouple input, the corresponding compensation wire should be used. 2. RTD input, 3 wires with low resistance and no difference should be used. 3. The input signal line should be far away from the power line of the instrument. Power supply and load lines to avoid noise interference. 4. Instrument power cord ...

1. The cleanliness and finish of the contact surface have a great impact on the working condition of the contact. When the surface of the contact is rough or there is excess material on the contact, it is easy to cause arcing and reduce the life of the contact. Therefore, the parts cleaning process should be improved to eliminate excess materials; Increasing the process of screening excess materials, ...
