Large Display Temperature Meters
The PD757 is a 2.3 in. high LED display temperature meter, housed in a heavy-duty, die-cast aluminum NEMA 4X enclosure. The PD755 is a 1.0 in. high LED display temperature meter housed in a rugged, impact-resistant, glass-filled polycarbonate NEMA 4X enclosure/ The PD756 is a 0.8 in. high LED display temperature meter housed in an explosion-proof NEMA 4 sand-cast aluminum enclosure.
With 4½ digits plus automatic lead zero blanking, all three meters are field selectable to accept J, K, T, E, R and S thermocouples and 100 ohm platinum RTD inputs. Additionally, all three can act as linearized temperature transmitters. Features include max/min temperature capture in Fahrenheit or Celsius and automatic cold junction reference fixed with no user calibration required. Field switchable 115/230 VAC is standard and options include 2 or 4 relays with built-in relay suppression for more consistent relay operation and isolated 4-20 mA output.
