1334 Flowmeter pulse transmitter
Additional electronics of the measurement system are required to satisfy the necessary specifications of the performance signal. In applications that need a high-amplitude 2-V to 24-V square wave signal, provides the Model 1334 with an economical driven coil as an alternative. In this application the technical certifications are separate from those for the regular model. Although the regular FPT is appropriate for 250 degF [121 degC], there are also available temperature levels up to 450 degF [232 degC]. Explosion-proof versions have an electrical interface of 1/2-in female national pipe thread (NPT) whereas the inherently secure model has an NPT center of 1 in man.
Approval classification options: ATEX, explosion-proof, Exd IIc, T4, –40 to 212 degF [–40 to 100 degC]. CSA, explosion-proof, Class I, Groups B, C, D; Class II, Groups E, F, G; Class III; Enclosure 4 (US and Canadian electrical code). CSA, intrinsically safe, Class I, Groups A, B, C, D; Class II, Groups E, F, G; Class III; Enclosure 4 (with approved barrier).
