Pantech Instruments - Process Controllers

Pantech's Programmable Microprocessor based Indicator cum Controller, model 802 is an ideal instrument for providing indication as well as controlling set points to various processes. It is designed to accept various process inputs ( Current, Voltage, RTD, Thermocouples, Resistances ) simultaneously i.e in UNIVERSAL manner or any one of these in PREDEFINED manner. When UNIVERSAL manner, The user can configure from the front keys to select any one of the input automatically. The user can also configure to set the range of linear inputs or calibrate the instrument without openint it. The model 802 can give maximum 4 relay outputs. All the contact output related specs like SETPOINT, ALARM TYPE, HYSTERISIS can be configured easily by the front panel keys itself. Retransmission facility is of course provided with all possible configurations allowed by front keys as usual. The instrument can be optionally equipped with serial communication facility to operate on MODBUS RTU protocols. Signle level password is there to keep the settings and configurations intact for the right user only. Low drift precession components are used for long term accuracy of the instruments. All instruments undergo a burn-in for better reliability.The instrument is available in different formats and sizes. Information regarding specification and size is given below.

BATCH CONTROLLERS FLOW INDICATORS Predefined Universal type MODEL 855 ( Microprocessor based & Fully Configurable ) Introduction Pantech Instruments Model 855V represents BATCH CONTROLLERS FLOW INDICATORS AND TOTALIZRS for flow applications where single flow signal is available. Model 855 is an ideal instrument for controlling amount of material flow in every batch. The input signal can be a currentvoltagelinear signal from a flow transmitter or pulses from turbine meters. It can also be UNIVERSAL input type, where user is allowed to select and configure the input signal. The analogue signal is square rooted if required, and similarly for digital pulses LitrePulses ratio ( i.e. K factor )can be adjusted to achieve precise measurement of flow and hence batching. The desired counts or the BATCH VALUE(S) are set through push button switches given in front of instrument. The relay(s) isare energised to start the flow and batch counter starts. When set batch counts are reached, relay(s) get de energised as per the batch-relay settings and the flow is stopped. The cycle repeats when start button is pressed again. The flow can be interrupted during the working cycle by pressing stop button and again started by pressing start.
