Description
ACT-2K Temperature Controller is provided with alarm control function on the basis of ACT-201 Digital Thermometer function, status display and alarm relay contacts output are provided, the upper and lower limit alarm points can be set, and return difference can be controlled, ACT-2K can also drive the relay output. Signal isolation design, without any interference, the standby lithium battery is built-in, which could work 4 to 6 years continuously. The acquisition pressure can be stabilized when the external power is broken off (but the output signal is invalid); the advantages of pressure controller are high control precision, fast response speed, stable performance, small performance, small in size, convenient installation, etc. It is the ideal substitute of electric-contact pressure gauge.
Applications
l Measurement accuracy is up to Grade 0.2, which can meet high precise pressure acquisition requirements
l Meet temperature display requirements of corrosivity, impact strength, vibration and other conditions
l Substitute of traditional pressure gauge, can be used as standard thermometer
Features
l Optional RS485 communication and 4~20mA current output
l The temperature sensor adopts imported temperature-sensing elements, with long service life, high precision and remarkable long-term stability.
l Magnetic pen induction button design
l Acquisition speed can be set
l Super power management technology, service life of battery can be 4 to 6 years
l Signal full isolation technology
l Anti electromagnetic interference and radio-frequency interference technology
l Epoxy resin sealing structure, shock and temperature resistance, which is applicable to be installed and used in severe site environment
l Pressure spring type structure ensures the temperature-sensing elements to be fully contacted with measured temperature field. The temperature response is fast to reveal the true value of measured temperature field.
