Pressure and vacuum transmitters from ace instruments are available in a stainless steel body with 0.25 per cent fs high accuracy. These pressure and vacuum transmitters are available salient features like 4-20 ma, 2-wire output, 17-4 ph stainless steel solid steel pressure port, no o-rings, and organics or welds exposed to the pressure media. These unique features of the pressure and vacuum transmitters provide leak proof all metal sealed pressure systems and can withstand more than 10 million pressure cycles. Some of the technical specifications of the ace pressure and vacuum transmitters are 1 percent error band; -40 c to +125 c operating temperature, etc. The company supplies transmitters in wide range including 0 to 1, 2, 4, 6, 8, 10, 16, 20, 25, 40, 100, 200, 300, 400, 700 bar and -1 to +4, -1 to +10 compound range. These pressure transmitters are useful for positive vacuum and pressure ranges. The company also provides a wide range of instruments to interface pressure transmitters such as digital pressure indicators, controllers, and data loggers with rs232/485 communication. Multi-channel pressure scanners from ace instruments are available in a single instrument useful to monitor pressure/vacuum at multiple places/ points/equipment. The scanners are provided with a direct recording facility onto an 80/132-column dot-matrix printer.
