MT100 Data Logger


The MT100 is a feature-packed process monitor for nearly any industrial application to replace traditional chart and circular recorders, digital and analog panel meters, and other less capable monitoring equipment. Its 10 isolated analog input channels are complemented by four logic channels that are programmable as either discrete or pulse inputs. The 10 analog channels may be programmed on a channel-by channel basis to measure voltage from ±20mV to 50V full scale across 12 ranges, thermocouple- or RTD-based temperature, or 4-20 or 0-20 mA current loops. Nearly all thermocouple types are supported; along with both PT100 and PT1000 RTDs. MT100 logic inputs detect state changes, while pulse inputs may be used for count and/or rate determinations. A separate trigger input allows the instrument to synchronize its measurements to external events. The MT100 measures humidity using either a built-in dry bulb/wet bulb calculation, or by using an optional humidity probe. All measurements are displayed in real time on its built-in color display, and may be simultaneously recorded to internal memory, a standard removable USB memory stick, or to a LAN-based file server. Each of four alarm outputs with flexible trigger definitions allow the MT100 to handle any alarm load up to 250 VAC /2 A, meaning that the MT100 can directly control most lights or audible alarms without external circuitry. If it’s connected to a PC on its LAN connection it can even send you an email during an alarm event.
