Longscale Indicators to read temperature values, usually remotely with RTD or thermocouple sensors supplied by the customer. RTD (Resistance Temperature Detector) indicators measure the change in resistance of the sensor. A 2 or 3 wire system may be used. Thermocouple indicators accept standard millivolt input signals. Cold junction compensation is provided and thermocouple break indication is incorporated.

Watt and Var meters self contained and are available to measure active power and reactive power in both balanced and unbalanced, single and 3 phase 3 or 4 wire systems. These Wattmeters are ideal for clear precise analog indication of power in applications such as power generation, industrial control panels and power distribution.

Phase Angle meters indicate the phase displacement between current and voltage. Used in applications where the phase angle must be monitored, for example with tariffs having VAr penalties, or to optimise generator power delivery. The measuring system comprises a moving coil indicator and a phase angle transducer

Where manual parallelling of two A.C. systems is necessary, the frequency of both systems can be monitored by a Synchroscope. The systems are synchronised when the pointer is stationary in the 12 o'clock position. The instrument is rated for continuous operation and connection, and silicon oil damping is employed.
