West Instruments, part of the Danaher group, now represented in South Africa by PREI Instrumentation has introduced a new line of temperature and process controllers. The 6500 is a simple, no frills 1/16 DIN controller with good display characteristics represented by a highly visible three-digit display and clear go/no go indication. Features include:
* Easy tune (PID) or On/Off.
* Setpoint lock.
* On control indicator.
* Alarm lock.
* Optional process alarm.
* Adjustable PV offset.
The benefits of the 6500 include its straightforward operator interface, simple set-up, ease of use and a fast 'up-time' over a defined range. 6100 + /8100+ /4100 + discrete temperature controllers.
The plus series controllers combine sophisticated functionality with in-built versatility and ease-of-use to provide a range of controllers to suit most process environments.
Because their inputs and outputs are all plug in, including relay, SSR, triac, linear and digital, they can be easily customised as required. Other features include: Jumper less configuration auto-hardware detect/set-up - to reduce set up times, new options for remote set point (RSP) and transmitter power supply (TxPSU), Configuration via PC/customisable operator menu and an improved, easy to use HMI - making set-up process quick and easy.
The 8800/8840 controllers offer the best in advanced process control for demanding applications. They provide a choice of simple 2-point (on/off) control, continuous PID control or VMD (valve motor drive).
These devices come fitted with four process outputs - either relays or up to two universal outputs that can be used for operating a solid state relay, linear current/voltage output or to power a two-wire transmitter. Features include: Front Comms port and PC configuration software, 2/3 analog inputs, valve motor drive with/without position feedback, maintenance manager and error list, self-tuning to the setpoint without oscillation, high visibility display sharing plain text or bar graphs.
