Ace Instruments offers Transmitter. This is a high accuracy transmitter for humidity, temperature and differential pressure. The transmitter has a dual line backlit LCD display with one line indicating the relative humidity percentage and the temperature alternately and the other line displaying the differential pressure. The humidity is displayed in % RH, the temperature in °C and the differential pressure either in Pascal"s or mm W/C. The measuring range of the humidity and temperature transmitter is -20 to +50°C for temperature, 0.0 to 100.0% RH and 0.0 to 100.0 mm W/C (0.0 to 981.0 Pascals). The transmitter has dual 4-20 mA output, which can be configured by user for any two of the three parameters. Additionally it has a RS485 Modbus RTU protocol digital output for communication. Multichannel scanners and data loggers are available to connect to the transmitters to connect number of transmitters to a single display cum recording unit with printing output directly onto a 80 column dot matrix printer. Data loggers can record the data from each of the transmitters in its memory and can be connected to a PC for download at any time convenient. Software for real time monitoring with graphs, tables and Excel sheet report generation is available for interfacing with PC.
