Signal conditioner for any transducer output
The 990 Signal conditioner from Hawker is for use with any transducer or transmitter input signal, providing a DIN mounted 4 digit LCD display of process variable, and an isolated analogue output
The user may span any part of the input signal.
The retransmission output is an analogue current and voltage proportional to the user calibrated input, as well as a digital transmission communications link via RS232.
The user can also select special functions such as a reverse acting output or display by setting options in the main menu.
The unit provides power for transducers or loop-powered transmitters or can accept a direct signal input for a transmitter with an external power supply, see the comprehensive connection drawings.
The 990 can be set to run in "simulator mode", where it effectively becomes a precision current or voltage source, this is useful for commissioning and diagnostic purposes.
Setting up is simple using only 2 pushbuttons and the LCD on the front of the unit, which contributes to very accurate and fast commissioning.
