THE INSTRUMENTOften it is more cost effective to replace a sensing head with one which is pre-calibrated at a testing station, thus reducing disruption of the measuring system. Technovation offers such an industry standard 4-20mA transmitter consisting of an electrochemical sensor, its associated circuitry and in a Ex-Proof housing and Ex-proof Sensor head. FEATURES The two-wire transmitter with a local display for measured parameter value allows the signal and power to be supplied on a single wire-pair by modulating the power supply current with the input signal source. The transmitter is immune to voltage drops from long runs and noise from motors, relays, actuators, switches, transformers and industrial equipment. APPLICATIONSEvery transmitter is supplied pre-calibrated for a customer specific range. The table below gives an indication of the gases/ranges offered. These transmitters can be connected to a DC system which supplies the DC Power for the loop. They could also be connected to stand alone controllers and PLCs and other data acquisition systems STANDARD SPECIFICATIONS Power Supply : 12 to 24 VDC Sensor Expected life : 2 years in air Sensor type : Electrochemical Duty : Continuous Operating temp : 5 oC to 45 oC Operating Humidity : 10 - 90 % RH Operating Pressure : Ambient Output impedance : 2 M Ohms Calibration : Via built in Span and Zero potentiometers. Housing : Cast Aluminum Ex-proof housing Sampling : Diffusion mode OR in flow through mode. Display : LCD Display. Size and weight : 120x120x90 mm. 1kg Connection size : M20 threaded cable entries for cable gland and for sensor head. As the minimum operating voltage for the transmitter is 12 VDC it will impose constraints on the total loop resistance in the external circuit, and this must be taken into account when choosing the supply voltage
