TC type J, K, T, R, S, E, B, and N or ±100mV input
1500V isolation
4 to 20mA DC output
USB-configured
The ST133 is a low-cost two-wire transmitter that isolates and converts a millivolt or thermocouple sensor input to a proportional 4-20mA control signal. Power is received from the output loop current. The transmitter performs signal linearization, cold-junction compensation, and lead-break detection functions.
High-voltage isolation separates the input from the output circuit. Isolation protects from surges, reduces noise, and eliminates ground loop errors. Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.
Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature measurement device. These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.
Easy setup and digital calibration via USB with Windows configuration software
Flexible thermocouple or millivolt input ranges (TC Type J, K, T, R, S, E, B, N or ±100mV)
1500V input isolation
24-bit A/D microcontroller
High accuracy, linearity, stability, and reliability
Low temperature drift (<75ppm/°C)
Fast response time (as low as 90ms)
User selectable filtering (none, low, med., high)
Supports reverse-acting (inverse) output
Selectable upscale or downscale operation for sensor errors and lead-break detection
Non-polarized output/power connection
Mounts in DIN Form B sensor heads
Shock (50g) and vibration (5g) resistant
Optional DIN rail adapter
Wide ambient operation (-40 to 80°C)
Hardened for harsh environments
CE compliant. UL/cUL Class 1 Div 2 Zone 2 approvals. Ex II 3 G Ex nA IIC T4 Gc -40°C < Ta < +80°C certified.
