Never before

Unique new Taylor THAN SCOPE Recorder plugs into panel-mounted manifold—an integral part of the sleeve. Model shown is the 2 pen recorder with continuous set point, automaticto-manual switch and output pressure indicator. "Servomatic" power pens provide 150 times more power than conventional bellows-actuated type, assuring life long accuracy.

Modern Process

Control Transmitter

Recorder

Controller settings are made from the front while recording. Gain, reset and PRE-ACT* dials are calibrated in specific units. Eliminates blind adjustments—settings and results are seen in one spot. . . the front of the panel. 102 A

Most dependable chart drive. Chart is held in positive position and driven by rectangular pins. Timing control is absolute, because chart drum is driven by a Gilmer, chain-like belt. No jerking, because new Rulon bearings cut power needs in half. 4", 30-day chart gives 3 hour visible record.

... sο Many Features in so Little Panel Space! Taylor's n e w 9 0 J Series TRANSCOPE Recorder is a giant step f o r w a r d in the d e v e l o p m e n t of convenience a n d compactness for m o d e r n instrument panels. N o other recorder, regardless of size, puts so m a n y f e a t u r e s in so little p a n e l space. • Front-of-Panel Control Settings let you make adjust­ ments easier, quicker, and better . . . from the front of the panel . . . while recording ! You can clearly see what you are doing, and the results, because the rec­ ord is continuous. • Stays on Automatic Control while the recorder is re­ moved for inspection. The unique Set Point Transmit­ ter remains plugged in the case, providing continuous fully automatic control. • Complete Indicating Control Station while recorder is removed. You see the variable. There's no need to shut down the process for instrument service or ad­ justments. Horizontal gage at top of recorder will show either process variable or air output to valve, as desired. • More Accurate Records. Responsiveness to transmitter output is 0 . 1 % ; and because of the very small pneumat­ ic displacement of the input capsule, the response is

practically instantaneous. You see more minute proc­ ess changes, so you can make optimum control set­ ting. SERVOMATIC power pens assure accurate pen position. • Interchangeable Components — all major assemblies, components and unit parts are completely interchange­ able. Both the TRANSCOPE Recorder and Controller may be changed in the field from simplest to most complete form. • Receives Three Variables to be recorded or indicated; has a set point transmitter, an automatic-to-manual switching lever, a cascade or process-output indica­ tor, and many other features . . . all in a compact case. • Complete Cascade System — a complete master-slave combination, in a smaller case than ever before. Per­ fect for direct control of composition, as well as the usual cascade control applications.
