Digi-Stem Meter for Rigid & Remote Sensors

Wahl’s Digi-Stem Thermometer and Transmitter Systems provide digital accuracy and reliability for temperature measurements in rugged industrial environments.

Our variety of rigid stems and remote interface connections accommodate most installations.
 
Remote Sensor Systems
Digi-Stem is offered in a variety of configurations to measure process temperatures remotely located from the meter. Optional remote sensor cables are available with different stem configurations. Stems can be specified for a variety of process connections or interfaces, including different thermowell adapters, penetration probes and immersion probes.

RTD or Thermocouple Output
Direct Connection: Wahl provides Digi-Stems with optional dual-element temperature sensors in the stem for direct connection to recorders and controllers. The primary sensor drives the local display while the dedicated  secondary sensor (RTD or Thermocouple) provides access to a 3- or 4-wire RTD circuit or a Thermocouple system interface. The connecting port is 1/2" NPT.

In Situ Calibration: Specify option DSA392M or DSA392HP for in situ calibration of Digi Stem Model DSTA200 without removal from a process. This  instrument has an RTD as the secondary sensor, which allows single-point calibration using Wahl’s highly accurate platinum-RTD Heat Prober 392A Meter. This provides the accuracy of a laboratory calibration, and saves time as well as money.

Transmitter Systems
Wahl offers loop-powered transmitter versions of Digi-Stem with continuous, digital, local display. The transmitter is an integral meter and electronics assembly in NEMA-4X housing with a 4-20mA, 2-wire current loop. Model DSXA300 has a temperature range of 0 to 300°F (-18 to 150°C), while Model DSX310’s range is 200 to 800°F (100 to 425°C). The transmitters incorporate all Digi-Stem family features, including stainless
steel construction, large digital display, reliability, and rugged construction.
