LTX-3000-WI: Isolated Two Wire Temperature Transmitter (In Weather proof enclosure field mounted).
Key Features
- Two wire design (supply and output on the same lines).
- Accepts RTD (Pt-100) / thermocouple / millivolt input.
- (4-20) mA non-isolated and isolated output.
- ZERO and SPAN adjustments for on-site calibration.
- Loop supply of 12 to 36VDC (with loop continuity LED).
- Saturation or open sensor current limited to 25Ma.
- Reverse polarity protection.
- Available in both Field mount and DIN rail mount versions.
- Special model ISO-12 for 4-20mA to 4-20mA isolation.
Application
- Carry thermocouple or RTD signals over long distance without noise and loss of accuracy.
- Eliminates the use of a costly compensating cable.
- Useful for converting other mV/Ohms signal to equivalent 4-20mA loop.
Technical Specification
| Parameters | Description |
|---|---|
| Input | Thermocouple, mV, RTD (Pt-100) or resistance signal from displacement, position or level sensor. |
| Range | Subject to specified input (User should specify the required range). |
| Output | (4-20) mA, two wire and loop powered |
| (calibrated linearly to the input signal). Isolated or Non-Isolated, as per model. | |
| Accuracy | ± 0.5 % to +/- 1% of the calibrated range or better including linearity, Hysterisis, and compensation error. |
| Calibration | On site using ZERO / SPAN presets (user settable using a small screw driver) |
| Zero Adjustment: +/-25% of the range (20 Turns). | |
| Span Adjustment: +/- 25% of the range (20 Turns). | |
| Loop supply (Vs) | 24VDC +/- 10% for isolated versions |
| Loop Status | The built in Red LED indicates the continuity status of the loop. |
| LED will not glow if the current loop is broken. | |
| Loop Resistance | 600 Ohms @ 24VDC (loop supply dependent). |
| Max. Load Resistance | RL Max = (Vs-12V) / 20 mA. |
| Isolation | Input and Output are Galvanically isolated (> 1KV) for isolated models |
| Burn Out Detection | The output shall saturate > 20mA (max. 25mA @ 24VDC loop supply) |
| Operating Temp. | 10 °C – 70 °C |
| Mounting | On-field or on site on the wall using 4 screws. |
| Sizes | 80 x 80 x 57 mm. |
