saturable, a.|ˈsætjʊərəb(ə)l|
[ad. L. saturābilis, f. saturāre to saturate: see -ble.]
a. Capable of saturation.
1570Levins Manip. 4/14 Saturable, saturabilis. 1701Grew Cosm. Sacra i. iii. 13 Consequently the Water would be Saturable with the same Quantity of any Salt. 1966Electronics 31 Oct. 44 The transmittance of the saturable absorber increases with the light flux. 1979Nature 19 Apr. 748/2 A stereospecific, saturable, high affinity binding site for 3H-diazepam has recently been characterised in membrane fractions isolated from the brains of mammals.
b. Of magnetic systems: capable of retaining a saturating magnetic field (see saturate v. 4 b). saturable reactor: an iron-cored coil whose impedance to alternating current can be varied by varying the direct current in an auxiliary winding so as to change the degree of magnetization of the core.
1944W. D. Cockrell Industr. Electronic Control x. 84 Another device by means of which we make deliberate use of the saturating effect for loads both large and small is the saturable reactor. 1956[see ferro-resonance s.v. ferro- 1 c]. 1962F. I. Ordway et al. Basic Astronautics v. 187 The flux gate magnetometer..consists essentially of a flux gate of two, identical, high-permeability, saturable coils, oppositely wound with identical coils. 1966McGraw-Hill Encycl. Sci. & Technol. XII. 37/1 Saturable-core reactors are used to control large alternating currents where rheostats are impractical. Theater light dimmers often employ saturable reactors. 1975D. G. Fink Electronics Engineers' Handbk. xiii. 82 The response time of saturable reactors is the combination of the time constants of the control circuit and of the gate-winding circuit.
Hence saturaˈbility.
