Temperature Controller For Fermentation Tank
Improving product quality: Temperature is a key factor influencing microbial metabolic pathways. Precise and stable temperature can ensure the efficient and consistent synthesis of products (such as antibiotics, enzymes, flavor substances), guaranteeing the stability of each batch of products. Increasing yield: Microorganisms grow and exhibit the highest metabolic activity at the optimal temperature. Precise temperature control can maximize the yield of target products, directly enhancing economic benefits.
- Product Introduction
Control temperature and pressure
Unambiguous and simple use
Mulit-level parametrizing, (access protected with passwords, which prevents "coincidental" changes)
Possibility of connecting into network (RS485)
Alarm for upper and lower limit
Simple assembly
Applied to food-processing field, esp. for temperature control in beer fermentation.
Instruction
1. Instruction for state of light:
1. Cool light is on. It indicates the controller is in state of cooling and the cooling valve is on.
If the cool light flashes, the controller is in state of cooling while the cooling valve is off.
Pre. Light is on. It indicates the pressure valve is on. Otherwise the valve is off.
Setup Light is on. It indicates the controller is under setting state.
If ºC light on, it displays in celcius degree. ºF light on, it displays in Fahrenheit degree.
Alarm When the light flashes, it indicates temperature exceeds the limit or there is error in parameter.
2. Button [SET]
Press shortly and enter temperature setting.
Press long and enter parameter adjustment of program menu.
Button [▲], [▼] change set value.
2.Pressure control
When the pressure reaches the up limit, the pressure valve opens and Pre. light is on. When reaches the lower limit, the pressure valve shuts off and Pre. light is off.
Alarm for false information:
-Er.S error in sensor
-Er.P error in program
When the above information appears, the controller will enter safe mode automatically.
3. Temperature setting
In normal display mode, press[SET] one minute and begin to the set temperature value. LED displays the set temperature and the light is on. Then press▲or▼to adjust temperature value. Press one time and the value will rise or fall 0.1C. Press ▲or▼ long, the set value will rise or fall quickly; afterwards press[SET] and withdraw from temperature setting.
Parameter setting of controller:
Parameter setting of controller: level 1
Press[SET] three seconds or longer, LED displays"PAS". Release[SET], press▲▲▼▼ in turns and then press[SET] to confirm, thus enter parameter setting of controller 1.Press▲or▼ to choose parameter and press [SET] to confirm. Press End to exit parameter setting.
