Description
Description
The DP9601 provides precise platinum resistancethermometer temperature measurement and loggingfor exacting applications in both laboratory and sitelocations. It is an exceptionally accurate and stabledigital thermometer particularly suitable for use withthermal calibration baths as a reference standard.Applications include medical, pharmaceutical, food,environmental testing, R&D and educationalestablishments.Displayed values and user information are indicated ona bright clear LED screen with diffused backlighting.Data can be displayed in °C, °F, K, and ohms as required;nine front panel push keys, the only user controls, areused in conjunction with the display screen. It is thisarrangement which makes for very simple and“friendly” operation.There are two input ports for 3- or 4-wire Pt100sensors; the instrument automatically recognizes3- or 4-wire configurations. The measured temperaturecan be displayed directly from one of the inputs ordifferentially between the two inputs. Differentialtemperature and the two individual channeltemperatures are displayed simultaneously.A flash drive USB port is provided to allow data to bestored and/or exported. PC software running inWindows® is provided as standard; it allowsprogramming of custom calibration, remote controland measure and logging functions.
SPECIFICATIONS Inputs/Ranges/Sensors
Type: Pt100 to IEC 751 (ITS 90 refers) -200 to 850°C (-328 to 1562°F) Ro = 100 ohm 3- or 4-wire connection with automatic recognition (with manual override)
Overall Accuracy: ±0.01°C ±0.0005% of span
Linearisation Conformity: Better than ±0.01°C Stability (vs Ambient Temperature): Better than 0.0025°C per 1°C ambient change
Warm-Up: Negligible under normal ambient conditions. Allow 5 to 10 minutes for full stability unless stored at low temperature, then 30 minutes minimum
Pt100 Sensor Current: 0.5 mA
Resolution of Data Display: 0.01
Variable Filter: Sampling rate selectable between 4 and 64 (measurements averaged per reading)
Measurement Units: °C, °F, K, Ω
Measurement Modes: A, B or A-B
Custom Calibration: Up to 10 calibration values can be allocated to Pt100 input A & B and to thermocouples input A & B; values are retained in non-volatile memory until replaced by user; ITS 90 or IPTS 68 coefficients can be used for custom calibration
Smart Sensor Connection: Correction values stored in connector
Null Function: Corrects differential temperature readout between two sensors to zero
Sensor Lead Resistance: 5 Ω each lead maximum
Logging: 8000 readings
Supply: Internal lithium Ion rechargeable batteries; mains 90 to 260V 50/60 Hz universal adaptor included; battery charge life up to 12 hours with full charge.
Series Mode Rejection: 60 dB @ 50 Hz (50 mV RMS applied)
Common Mode Rejection: 30V RMS applied between input and earth produces no measurable effect
Display: 128 x 64 pixel character OLED screen with diffused backlighting; wide viewing angle, high contrast (adjustable)
Front Panel Controls: 9 membrane push-keys to control all instrument functions
Mechanical/Case: Metal bench top case/adjustable tilt
Dimensions: Overall 190 W x 70 H x 250 mm D (7.5 x 2.75 x 9.85")
Weight: 3 kg (6.61 lb) approx
Input Connections: 2 x Pt100 via D type connectors
USB Serial: Isolated, 38400 Baud, 8 data, no parity, 1 stop bit
Communications: Remote control and measure
PC Software (Standard): Supplied as standard on CD-ROM. Remote control and measure: log readings to file/ download to PC/programming corrections
Analog Output (Standard): User programmable, 0 to 1 Vdc
Application Note: Inputs are not isolated in the instrument, which is primarily designed for laboratory applications and site calibration of industrial temperature sensors. Probes connected to the instrumentmust therefore be isolated from high voltage pick-up.
Precision Pt100 Probes: 304 Stainless steel probes, 6 mm Dia. with 2 m screened PTFE lead Pt100 Probes and connector
DP9600-L250: 250 mm (9.85") L, -50 to 250°C (-58 to 482°F)
