Series 340 is a line of small-bore submersible level transducers that incorporates application-specific integrated circuit (ASIC) technology, which diminishes the effects of temperature changes and improves overall accuracy. The transducers provide a total error band (TEB) of 0.25% over the entire compensated temperature range of -4 F to 140 F. Pressure Systems, Inc. pressuresystems.com Write 321 on PE card

DP41-B is a 1/8-DIN meter with an accuracy of up to ±0.005% of reading, and up to 166 readings/sec. The unit handles dc voltage and current, nine thermocouple types, multiple RTDs, potentiometric inputs, and signals from strain gauge transducers such as load cells and pressure sensors. The panel meter features user-programmable, 10-point linearization, built in excitation, and four isolated open-collector outputs. OMEGA Engineering, Inc. omega.com Write 322 on PE card

29A is a 10 MHz direct digital synthesis (DDS) function generator. Features include 10 ppm frequency accuracy with 7-digit resolution; multiunit phase locking; trigger, burst, gate, and sweep functions; amplitude modulation (AM), frequency-shift-keying (FSK) and frequency hopping; store and recall of nine instrument setups; and RS-232 and IEEE-488 (GPIB) interfaces.
