The LDM-A model uses advanced analog electronics, and has a 9-pin D-subminiature, 15-pin high density D-subminiature, or Bendix® electrical connector that can mount directly to the mating electrical connectors of MKS 740B, 742B, 750B, 752B, 840B, 842B, 850B, 852B, 870B, 872B, AA07A and AA08A Baratron pressure transducers. For applications with space constraints around the gas line, it can also be panel-mounted remotely and connected to the transducer via a separate cable. Pressure ranges from 10 Torr to 3000 PSI are available, as are a wide range of options to allow custom configuration to nearly any requirement. Versions with 0-10 VDC or 0-5 VDC output have a high-visibility red LED display and operate on +13 to 32VDC input power, while models with 4-20 mA output signal use a large LCD display and require +13 to 36 VDC excitation.

The LDM-D is a low-cost model that uses microprocessorcontrolled electronics to generate a brilliant red LED display that can be easily switched to show the transducer’s pressure in alternate engineering units such as bar, kPa, and Torr/mm Hg. The LDM-D operates on input voltages of +12 to +32 VDC, and it has a 0-10 VDC output.

The LDM-D also can be mounted directly to compatible MKS 740B, 742B, 750B, 752B, 840B, 842B, 850B, 852B, 870B, 872B, AA07A and AA08A Baratron pressure transducers without requiring a separate power and signal cable to the host assuming that the transducer has a 15-pin high-density D-subminiature electrical connector. Pressure ranges of 1000 Torr (absolute), 60 PSIA, and 100 PSIA are available, as is mounting hardware to permit remote panel mounting and cables to connect to the pressure transducer.
