Isolated Probe System
340W SPECIFICATIONS
Reference conditions: zero-based spans, ambient temperature 28ºC (82ºF), D/A trim values equal to span end points, silicon fill, 316L SS diaphragm, one-second damping.
Accuracy - ±0.25% of calibrated span for spans from 1:1 to 10:1 of URL
- ±(0.178+0.0072[URL/span])% of calibrated span for spans from 10:1 to 45:1 of URL
Note: Accuracy includes the combined effects of linearity, repeatability, and hysteresis
Ambient Temperature Effect - ±0.25% of URL per 28ºC (82ºF) shift
Temperature Limits
Sensor Assembly - -40 to 257ºF (-40 to 125ºC)
Electronics
Static Pressure Effect
Zero - Eliminated at operating pressure
Span- Correctable to 0.2% per 150 psi (1034 kPa)
Maximum Working Pressure
Note: MWP is the maximum pressure (static or otherwise) that can be applied to the cell without damage.
Stability
Zero - 0.1% of URL for 12 months
Span
Humidity - 0-100% relative humidity, noncondensing
Vibration Effect - Less than ±0.05% of URL per G for 0-60 Hz in any axis up to 2 Gs maximum
Power Supply Effect - Less than ±0.005% of output span per volt
EMI/RFI Susceptibility - Less than ±0.25% of URL at 30 V/m, 30MHz-1Gz

Zero Elevation & Suppression - The range may be set anywhere between the LRL and URL of the transmitter, as long as the calibrated span does not exceed the minimum allowable span. Zero and soan in the XTC are noninteractive.
Electronic Damping - Adjustable between 0 and 30 seconds
Transmitter Outputs - Analog, two-wire mA
- Digital, HART Communications
- Optional Transient Suppressor
Power Supply Requirements - Minimum Terminal to Terminal Compliance Voltage - +10Vdc
- Maximum Terminal to Terminal Voltage - +42Vdc
- Maximum Load - R=50º(supply voltage) - 500 ohms
Note: To ensure digital communication, HART imposes the following restrictions on the loop: 250< R < 1100 ohms, ripple < 0.2 Vp-p ac between 47 and 125 Hz, noise < 0.6 mVrms.
Local Indication - Optional 4-1/2 digit Smart Display
Surge Protection (with optional transient suppressor) - Maximum Clamping Voltage (either terminal to case)
- DC - 68V
- 100kVuS surge - 70 Vp
- 1000 kVu surge - 120 Vp
Recommended Wire Type - <5000 ft(1524m): Belden 8641, 24AWG
- >5000 ft(1524m): Belden 8762, 20AWG
