PDF of this product overview


The Thermo Controller Module

This is a digital microprocessor based unit for heating optical crystal ovens and PID control mode. The instrument has one semiconductor switch output and one input for RTD temperature probe. The module is equipped with 4 multi-function buttons, a 16x2 character LCD display and 2 LED signals. The embedded current-loop receiver and the 16bit pulse width modulator provide long-term stability of less than 0.05o rms.

Crystal Oven

The oven consists of nonlinear crystal holder, temperature-to-current converter, coaxial heater providing homogenous temperature distribution over the crystal holder and housing of thermo isolating material. The diameter of the standard oven permits accommodation of a nonlinear crystal with dimension 5x5x(crystal length). For bigger crystal cross section please contact Deltronic Crystal Ind. Inc.
