![]() Input Filter: RC filter plus variable digital filter (none, low, medium, high). Input Over-Voltage Protection: Bipolar Transient Voltage Suppression (TVS) and diode clamping. Lead Break (Sensor Burnout) Detection: Upscale/downscale. Two 24-bit Sigma Delta ADCs (only 16-bits used). Transient voltage suppression on power and data lines. IMPORTANT: To prevent ground loop error between a grounded PC and a grounded input signal, Acromag strongly recommends use of a USB isolator like Acromag’s USB-Isolator when configuring a DT230 Series transmitter. Learn more about the DT Series and view all models > RTD / Resistance Input Two-Wire Dual Transmitter Performance Specifications They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions. These transmitters can withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. The Android app enables setup with mobile devices.Īdvanced signal processing capabilities, variable range input/output, and convenient USB programming make this instrument very versatile. Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software. Isolation protects from surges, reduces noise, and eliminates ground loop errors. High-voltage isolation separates all input and output circuits from each other. ![]() Power is received from the output loop current or a DC supply when using a three-wire connection. The DT235 model is a two-wire dual transmitter that isolates and converts RTD or linear resistance sensor inputs to a proportional 4-20mA control signal.

Tighter accuracies are available on special order.ĭiscounts offered on bulk purchases. 0.75% guaranteed accuracy Minco guarantees a system accuracy (current signal vs temperature) of 0.75% of span when you order specially calibrated Temptrans with any RTD in the HVAC/R Sensors Section. ![]() When you calibrate the sensor and transmitter as a set, the sensor error disappears, reducing system error to ☑.0☌ over the full range - all for a nominal extra cost. Total system error would be ☑.3☌ at 0☌ and ☓.8☌ at 500☌. The RTD interchangeability contributes an additional error of ☐.3☌ at 0☌ and ☒.8☌ at 500☌. The transmitter itself is accurate to ☑.0☌ (☐.2% of span, including calibration accuracy and linearity). For example, consider a transmitter with a range of 0 to 500☌. If you order Minco Temptrans calibrated to the actual resistance of the RTD (as measured in Minco’s metrology lab), this effectively subtracts the sensor tolerance from system accuracy specifications. Total system error includes the tolerance of both the transmitter and the RTD sensor. Standard transmitters are calibrated to the nominal resistance values of the RTD at the zero and span points. These units include the Temptran™ 4 to 20 mA Transmitters Listing is for one brand new Minco TT611PD1XD RTD 100 Ω Temperature Sensor w/ Enclosure.
