Product Description
2.1
General
The TMP-3000 Smart Positioner not only precisely controls the valve opening according
to the current signal of 4 ~ 20mA DC input from the controller or the central control
room, but also performs the auto calibration by the computation action of the built-in
high performance microprocessor and PD control. It is a highly reliable positioner that
performs various powerful functions such as optimum control.

Main Features and Functions
➢
In case of Fail Freeze optional product, it maintains the current valve position without
any additional equipment such as lockup valve or solenoid valve in case of input
signal and pneumatic failure.
➢
Back light function LCD is attached so you can check the status of the positioner
directly in the field.
➢
Four adjustment buttons and unique functions of the buttons are applied in the
same way throughout the firmware, so it is very easy to use.
➢
The initialization time is very short, which minimizes the change of valve stroke in
case of temporary power failure and improves system stability.
➢
Very strong against vibration and can be used in extremely high vibration areas.
➢
The change in supply pressure during use has almost no effect on the adjustability
of the positioner.
➢
Auto calibration is very simple, so first time users can handle the product easily.
➢
Compact size makes it easy to attach to small actuators.
➢
Very low air consumption which allows large plants to reduce their operating costs.
➢
The valve system can be stabilized by outputting an analog feedback signal.
➢
Variable valve flow control characteristics such as Linear, Quick Open, Equal % can be
changed.
➢
It is possible to implement special flow control characteristics by specifying 16 points
at user's discretion.
➢
You can minimize valve leakage by setting the sealing function of Tight Shut-Off /
On.
➢
Half-interval control (Split Range) is available such as 4 ~ 12mA and 12 ~ 20Ma.
➢
You can change Zero and Span freely through Hand Calibration function.
➢
By manual operation, valve can be operated arbitrarily irrespective of input signal, so
